		82	=item connect => [$host, $service] [C<fh> or C<connect> MANDATORY]
		83
		84	Try to connect to the specified host and service (port), using
		85	C<AnyEvent::Socket::tcp_connect>. The C<$host> additionally becomes the
		86	default C<peername>.
		87
		88	You have to specify either this parameter, or C<fh>, above.
		89
		90	It is possible to push requests on the read and write queues, and modify
		91	properties of the stream, even while AnyEvent::Handle is connecting.
		92
		93	When this parameter is specified, then the C<on_prepare>,
		94	C<on_connect_error> and C<on_connect> callbacks will be called under the
		95	appropriate circumstances:
		96
		97	=over 4
		98
		99	=item on_prepare => $cb->($handle)
		100
		101	This (rarely used) callback is called before a new connection is
		102	attempted, but after the file handle has been created. It could be used to
		103	prepare the file handle with parameters required for the actual connect
		104	(as opposed to settings that can be changed when the connection is already
		105	established).
		106
		107	The return value of this callback should be the connect timeout value in
		108	seconds (or C<0>, or C<undef>, or the empty list, to indicate the default
		109	timeout is to be used).
		110
		111	=item on_connect => $cb->($handle, $host, $port, $retry->())
		112
		113	This callback is called when a connection has been successfully established.
		114
		115	The actual numeric host and port (the socket peername) are passed as
		116	parameters, together with a retry callback.
		117
		118	When, for some reason, the handle is not acceptable, then calling
		119	C<$retry> will continue with the next conenction target (in case of
		120	multi-homed hosts or SRV records there can be multiple connection
		121	endpoints). When it is called then the read and write queues, eof status,
		122	tls status and similar properties of the handle are being reset.
		123
		124	In most cases, ignoring the C<$retry> parameter is the way to go.
		125
		126	=item on_connect_error => $cb->($handle, $message)
		127
		128	This callback is called when the conenction could not be
		129	established. C<$!> will contain the relevant error code, and C<$message> a
		130	message describing it (usually the same as C<"$!">).
		131
		132	If this callback isn't specified, then C<on_error> will be called with a
		133	fatal error instead.
		134
		135	=back
		136
		137	=item on_error => $cb->($handle, $fatal, $message)
		138
		139	This is the error callback, which is called when, well, some error
		140	occured, such as not being able to resolve the hostname, failure to
		141	connect or a read error.
		142
		143	Some errors are fatal (which is indicated by C<$fatal> being true). On
		144	fatal errors the handle object will be destroyed (by a call to C<< ->
		145	destroy >>) after invoking the error callback (which means you are free to
		146	examine the handle object). Examples of fatal errors are an EOF condition
		147	with active (but unsatisifable) read watchers (C<EPIPE>) or I/O errors. In
		148	cases where the other side can close the connection at their will it is
		149	often easiest to not report C<EPIPE> errors in this callback.
		150
		151	AnyEvent::Handle tries to find an appropriate error code for you to check
		152	against, but in some cases (TLS errors), this does not work well. It is
		153	recommended to always output the C<$message> argument in human-readable
		154	error messages (it's usually the same as C<"$!">).
		155
		156	Non-fatal errors can be retried by simply returning, but it is recommended
		157	to simply ignore this parameter and instead abondon the handle object
		158	when this callback is invoked. Examples of non-fatal errors are timeouts
		159	C<ETIMEDOUT>) or badly-formatted data (C<EBADMSG>).
		160
		161	On callback entrance, the value of C<$!> contains the operating system
		162	error code (or C<ENOSPC>, C<EPIPE>, C<ETIMEDOUT>, C<EBADMSG> or
		163	C<EPROTO>).
		164
		165	While not mandatory, it is I<highly> recommended to set this callback, as
		166	you will not be notified of errors otherwise. The default simply calls
		167	C<croak>.
		168
		169	=item on_read => $cb->($handle)
		170
		171	This sets the default read callback, which is called when data arrives
		172	and no read request is in the queue (unlike read queue callbacks, this
		173	callback will only be called when at least one octet of data is in the
		174	read buffer).
		175
		176	To access (and remove data from) the read buffer, use the C<< ->rbuf >>
		177	method or access the C<< $handle->{rbuf} >> member directly. Note that you
		178	must not enlarge or modify the read buffer, you can only remove data at
		179	the beginning from it.
		180
		181	When an EOF condition is detected then AnyEvent::Handle will first try to
		182	feed all the remaining data to the queued callbacks and C<on_read> before
		183	calling the C<on_eof> callback. If no progress can be made, then a fatal
		184	error will be raised (with C<$!> set to C<EPIPE>).
		185
		186	Note that, unlike requests in the read queue, an C<on_read> callback
		187	doesn't mean you I<require> some data: if there is an EOF and there
		188	are outstanding read requests then an error will be flagged. With an
		189	C<on_read> callback, the C<on_eof> callback will be invoked.

		290	=item keepalive => <boolean>
		291
		292	Enables (default disable) the SO_KEEPALIVE option on the stream socket:
		293	normally, TCP connections have no time-out once established, so TCP
		294	conenctions, once established, can stay alive forever even when the other
		295	side has long gone. TCP keepalives are a cheap way to take down long-lived
		296	TCP connections whent he other side becomes unreachable. While the default
		297	is OS-dependent, TCP keepalives usually kick in after around two hours,
		298	and, if the other side doesn't reply, take down the TCP connection some 10
		299	to 15 minutes later.
		300
		301	It is harmless to specify this option for file handles that do not support

		303	is usually a good idea.
