		744
		745	Makes a regex match against the regex object C<$accept> and returns
		746	everything up to and including the match.
		747
		748	Example: read a single line terminated by '\n'.
		749
		750	$handle->push_read (regex => qr<\n>, sub { ... });
		751
		752	If C<$reject> is given and not undef, then it determines when the data is
		753	to be rejected: it is matched against the data when the C<$accept> regex
		754	does not match and generates an C<EBADMSG> error when it matches. This is
		755	useful to quickly reject wrong data (to avoid waiting for a timeout or a
		756	receive buffer overflow).
		757
		758	Example: expect a single decimal number followed by whitespace, reject
		759	anything else (not the use of an anchor).
		760
		761	$handle->push_read (regex => qr<^[0-9]+\s>, qr<[^0-9]>, sub { ... });
		762
		763	If C<$skip> is given and not C<undef>, then it will be matched against
		764	the receive buffer when neither C<$accept> nor C<$reject> match,
		765	and everything preceding and including the match will be accepted
		766	unconditionally. This is useful to skip large amounts of data that you
		767	know cannot be matched, so that the C<$accept> or C<$reject> regex do not
		768	have to start matching from the beginning. This is purely an optimisation
		769	and is usually worth only when you expect more than a few kilobytes.
		770
		771	Example: expect a http header, which ends at C<\015\012\015\012>. Since we
		772	expect the header to be very large (it isn't in practise, but...), we use
		773	a skip regex to skip initial portions. The skip regex is tricky in that
		774	it only accepts something not ending in either \015 or \012, as these are
		775	required for the accept regex.
		776
		777	$handle->push_read (regex =>
		778	qr<\015\012\015\012>,
		779	undef, # no reject
		780	qr<^.*[^\015\012]>,

		816	=item AnyEvent::Handle::register_read_type type => $coderef->($self, $cb, @args)
		817
		818	This function (not method) lets you add your own types to C<push_read>.
		819
		820	Whenever the given C<type> is used, C<push_read> will invoke the code
		821	reference with the handle object, the callback and the remaining
		822	arguments.
		823
		824	The code reference is supposed to return a callback (usually a closure)
		825	that works as a plain read callback (see C<< ->push_read ($cb) >>).
		826
		827	It should invoke the passed callback when it is done reading (remember to
		828	pass C<$self> as first argument as all other callbacks do that).
		829
		830	Note that this is a function, and all types registered this way will be
		831	global, so try to use unique names.
		832
		833	For examples, see the source of this module (F<perldoc -m AnyEvent::Handle>,
		834	search for C<register_read_type>)).
