		146
		147	Very perl extension is a perl class. A separate perl object is created
		148	for each terminal and each extension and passed as the first parameter to
		149	hooks. So extensions can use their C<$self> object without having to think
		150	about other extensions, with the exception of methods and members that
		151	begin with an underscore character C<_>: these are reserved for internal
		152	use.
		153
		154	Although it isn't a C<urxvt::term> object, you can call all methods of the
		155	C<urxvt::term> class on this object.

		165
		166	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		167
		168	Dynamically enable the given hooks (named without the C<on_> prefix) for
		169	this extension, replacing any previous hook. This is useful when you want
		170	to overwrite time-critical hooks only temporarily.
