		144
		145	Very perl extension is a perl class. A separate perl object is created
		146	for each terminal and each extension and passed as the first parameter to
		147	hooks. So extensions can use their C<$self> object without having to think
		148	about other extensions, with the exception of methods and members that
		149	begin with an underscore character C<_>: these are reserved for internal
		150	use.
		151
		152	Although it isn't a C<urxvt::term> object, you can call all methods of the
		153	C<urxvt::term> class on this object.
		154
		155	It has the following methods and data members:
		156
		157	=over 4

		162	extension. This member I<must not> be changed in any way.
		163
		164	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		165
		166	Dynamically enable the given hooks (named without the C<on_> prefix) for
		167	this extension, replacing any previous hook. This is useful when you want
		168	to overwrite time-critical hooks only temporarily.
		169
