+=head1 A FEW NOTES ON UNICODE AND PERL
+Since this often leads to confusion, here are a few very clear words on
+how Unicode works in Perl, modulo bugs.
+=over 4
+=item 1. Perl strings can store characters with ordinal values > 255.
+This enables you to store Unicode characters as single characters in a
+Perl string - very natural.
+=item 2. Perl does I<not> associate an encoding with your strings.
+Unless you force it to, e.g. when matching it against a regex, or printing
+the scalar to a file, in which case Perl either interprets your string as
+locale-encoded text, octets/binary, or as Unicode, depending on various
+settings. In no case is an encoding stored together with your data, it is
+I<use> that decides encoding, not any magical metadata.
+=item 3. The internal utf-8 flag has no meaning with regards to the
+encoding of your string.
+Just ignore that flag unless you debug a Perl bug, a module written in
+XS or want to dive into the internals of perl. Otherwise it will only
+confuse you, as, despite the name, it says nothing about how your string
+is encoded. You can have Unicode strings with that flag set, with that
+flag clear, and you can have binary data with that flag set and that flag
+clear. Other possibilities exist, too.
+If you didn't know about that flag, just the better, pretend it doesn't
+exist.
+=item 4. A "Unicode String" is simply a string where each character can be
+validly interpreted as a Unicode codepoint.
+If you have UTF-8 encoded data, it is no longer a Unicode string, but a
+Unicode string encoded in UTF-8, giving you a binary string.
+=item 5. A string containing "high" (> 255) character values is I<not> a UTF-8 string.
+It's a fact. Learn to live with it.
+=back
+I hope this helps :)
 =head1 OBJECT-ORIENTED INTERFACE
 The object oriented interface lets you configure your own encoding or
 decoding style, within the limits of supported formats.
    my $json = JSON::XS->new->utf8->space_after->encode ({a => [1,2]})
    => {"a": [1, 2]}
 =item $json = $json->ascii ([$enable])
+=item $enabled = $json->get_ascii
 If C<$enable> is true (or missing), then the C<encode> method will not
 generate characters outside the code range C<0..127> (which is ASCII). Any
-unicode characters outside that range will be escaped using either a
+Unicode characters outside that range will be escaped using either a
 single \uXXXX (BMP characters) or a double \uHHHH\uLLLLL escape sequence,
 as per RFC4627. The resulting encoded JSON text can be treated as a native

+Unicode string, an ascii-encoded, latin1-encoded or UTF-8 encoded string,
 or any other superset of ASCII.
 If C<$enable> is false, then the C<encode> method will not escape Unicode
 characters unless required by the JSON syntax or other flags. This results
 in a faster and more compact format.
   JSON::XS->new->ascii (1)->encode ([chr 0x10401])
   => ["\ud801\udc01"]
 =item $json = $json->latin1 ([$enable])
+=item $enabled = $json->get_latin1
 If C<$enable> is true (or missing), then the C<encode> method will encode
 the resulting JSON text as latin1 (or iso-8859-1), escaping any characters
 outside the code range C<0..255>. The resulting string can be treated as a
-latin1-encoded JSON text or a native unicode string. The C<decode> method

+expects Unicode, which is a strict superset of latin1.
 If C<$enable> is false, then the C<encode> method will not escape Unicode
 characters unless required by the JSON syntax or other flags.
 The main use for this flag is efficiently encoding binary data as JSON
 text, as most octets will not be escaped, resulting in a smaller encoded
 size. The disadvantage is that the resulting JSON text is encoded
 in latin1 (and must correctly be treated as such when storing and
-transfering), a rare encoding for JSON. It is therefore most useful when
+transferring), a rare encoding for JSON. It is therefore most useful when
 you want to store data structures known to contain binary data efficiently
 in files or databases, not when talking to other JSON encoders/decoders.

   => ["\x{89}\\u0abc"]    # (perl syntax, U+abc escaped, U+89 not)
 =item $json = $json->utf8 ([$enable])
+=item $enabled = $json->get_utf8
 If C<$enable> is true (or missing), then the C<encode> method will encode
 the JSON result into UTF-8, as required by many protocols, while the
 C<decode> method expects to be handled an UTF-8-encoded string.  Please
 note that UTF-8-encoded strings do not contain any characters outside the
 range C<0..255>, they are thus useful for bytewise/binary I/O. In future
 versions, enabling this option might enable autodetection of the UTF-16
 and UTF-32 encoding families, as described in RFC4627.
 If C<$enable> is false, then the C<encode> method will return the JSON
-string as a (non-encoded) unicode string, while C<decode> expects thus a

   $object = JSON::XS->new->decode (decode "UTF-32LE", $jsontext);
 =item $json = $json->pretty ([$enable])
+=item $enabled = $json->get_pretty
 This enables (or disables) all of the C<indent>, C<space_before> and
 C<space_after> (and in the future possibly more) flags in one call to
 generate the most readable (or most compact) form possible.

    }
 =item $json = $json->indent ([$enable])
+=item $enabled = $json->get_indent

 format as output, putting every array member or object/hash key-value pair

 =item $json = $json->space_before ([$enable])
+=item $enabled = $json->get_space_before
 If C<$enable> is true (or missing), then the C<encode> method will add an extra
 optional space before the C<:> separating keys from values in JSON objects.
 If C<$enable> is false, then the C<encode> method will not add any extra
 Example, space_before enabled, space_after and indent disabled:
    {"key" :"value"}
 =item $json = $json->space_after ([$enable])
+=item $enabled = $json->get_space_after
 If C<$enable> is true (or missing), then the C<encode> method will add an extra
 optional space after the C<:> separating keys from values in JSON objects
 and extra whitespace after the C<,> separating key-value pairs and array
 members.
 Example, space_before and indent disabled, space_after enabled:
    {"key": "value"}
+=item $json = $json->relaxed ([$enable])
+=item $enabled = $json->get_relaxed
+If C<$enable> is true (or missing), then C<decode> will accept some
+extensions to normal JSON syntax (see below). C<encode> will not be
+affected in anyway. I<Be aware that this option makes you accept invalid
+JSON texts as if they were valid!>. I suggest only to use this option to

+   ]
+   {
+      "k1": "v1",
+      "k2": "v2", <- this comma not normally allowed

+        # neither this one...
+  ]
+=back
 =item $json = $json->canonical ([$enable])
+=item $enabled = $json->get_canonical
 If C<$enable> is true (or missing), then the C<encode> method will output JSON objects
 by sorting their keys. This is adding a comparatively high overhead.
 If C<$enable> is false, then the C<encode> method will output key-value
 pairs in the order Perl stores them (which will likely change between runs
 of the same script).
 This option is useful if you want the same data structure to be encoded as
 the same JSON text (given the same overall settings). If it is disabled,
-the same hash migh be encoded differently even if contains the same data,
+the same hash might be encoded differently even if contains the same data,
 as key-value pairs have no inherent ordering in Perl.
 This setting has no effect when decoding JSON texts.
 =item $json = $json->allow_nonref ([$enable])
+=item $enabled = $json->get_allow_nonref
 If C<$enable> is true (or missing), then the C<encode> method can convert a
 non-reference into its corresponding string, number or null JSON value,
 which is an extension to RFC4627. Likewise, C<decode> will accept those JSON
 values instead of croaking.
    JSON::XS->new->allow_nonref->encode ("Hello, World!")
    => "Hello, World!"
 =item $json = $json->allow_blessed ([$enable])
+=item $enabled = $json->get_allow_bless
 If C<$enable> is true (or missing), then the C<encode> method will not
 barf when it encounters a blessed reference. Instead, the value of the
-B<convert_blessed> option will decide wether C<null> (C<convert_blessed>
+B<convert_blessed> option will decide whether C<null> (C<convert_blessed>

 encoded. Has no effect on C<decode>.
 If C<$enable> is false (the default), then C<encode> will throw an
 exception when it encounters a blessed object.
 =item $json = $json->convert_blessed ([$enable])
+=item $enabled = $json->get_convert_blessed
 If C<$enable> is true (or missing), then C<encode>, upon encountering a
 blessed object, will check for the availability of the C<TO_JSON> method
 on the object's class. If found, it will be called in scalar context
 and the resulting scalar will be encoded instead of the object. If no

 support this in any way, so you need to make sure your data never looks
 like a serialised Perl hash.
 Typical names for the single object key are C<__class_whatever__>, or
 C<$__dollars_are_rarely_used__$> or C<}ugly_brace_placement>, or even
       { __widget__ => $self->{id} }
    }
 =item $json = $json->shrink ([$enable])
+=item $enabled = $json->get_shrink
 Perl usually over-allocates memory a bit when allocating space for
 strings. This flag optionally resizes strings generated by either
 C<encode> or C<decode> to their minimum size possible. This can save
 memory when your JSON texts are either very very long or you have many
 strings that look like integers or floats into integers or floats
 internally (there is no difference on the Perl level), saving space.

+=item $max_depth = $json->get_max_depth

 or decoding. If the JSON text or Perl data structure has an equal or
 higher nesting level then this limit, then the encoder and decoder will
 stop and croak at that point.

 See SECURITY CONSIDERATIONS, below, for more info on why this is useful.

+=item $max_size = $json->get_max_size
 Set the maximum length a JSON text may have (in bytes) where decoding is
 being attempted. The default is C<0>, meaning no limit. When C<decode>
 is called on a string longer then this number of characters it will not
 attempt to decode the string but throw an exception. This setting has no

 circumstances automatically, preserving round-tripping characteristics

 usually a good indication of the size of the resources required to decode
 it into a Perl structure. While JSON::XS can check the size of the JSON
 text, it might be too late when you already have it in memory, so you
 might want to check the size before you accept the string.
 And last but least, something else could bomb you that I forgot to think
 of. In that case, you get to keep the pieces. I am always open for hints,

 you are vulnerable to some common attack vectors (which really are browser
 design bugs, but it is still you who will have to deal with it, as major
 browser developers care only for features, not about doing security
 right).
+=head1 THREADS
+This module is I<not> guaranteed to be thread safe and there are no
+plans to change this until Perl gets thread support (as opposed to the
+horribly slow so-called "threads" which are simply slow and bloated
+process simulations - use fork, its I<much> faster, cheaper, better).
+(It might actually work, but you have been warned).
 =head1 BUGS
 While the goal of this module is to be correct, that unfortunately does
 not mean its bug-free, only that I think its design is bug-free. It is
 still relatively early in its development. If you keep reporting bugs they
 will be fixed swiftly, though.
+Please refrain from using rt.cpan.org or any other bug reporting
+service. I put the contact address into my modules for a reason.
