		140	=head2 Extension Objects
		141
		142	Very perl extension is a perl class. A separate perl object is created
		143	for each terminal and each extension and passed as the first parameter to
		144	hooks. So extensions can use their C<$self> object without having to think
		145	about other extensions, with the exception of methods and members that
		146	begin with an underscore character C<_>: these are reserved for internal
		147	use.
		148
		149	Although it isn't a C<urxvt::term> object, you can call all methods of the
		150	C<urxvt::term> class on this object.
		151

		159	extension. This member I<must not> be changed in any way.
		160
		161	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		162
		163	Dynamically enable the given hooks (named without the C<on_> prefix) for
		164	this extension, replacing any previous hook. This is useful when you want
		165	to overwrite time-critical hooks only temporarily.
		166
