		137	=head2 Extension Objects
		138
		139	Very perl extension is a perl class. A separate perl object is created
		140	for each terminal and each extension and passed as the first parameter to
		141	hooks. So extensions can use their C<$self> object without having to think
		142	about other extensions, with the exception of methods and members that
		143	begin with an underscore character C<_>: these are reserved for internal
		144	use.
		145
		146	Although it isn't a C<urxvt::term> object, you can call all methods of the
		147	C<urxvt::term> class on this object.
		148
		149	It has the following methods and data members:
		150
		151	=over 4

		155	Returns the C<urxvt::term> object associated with this instance of the
		156	extension. This member I<must not> be changed in any way.
		157
		158	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		159
		160	Dynamically enable the given hooks (named without the C<on_> prefix) for
		161	this extension, replacing any previous hook. This is useful when you want
		162	to overwrite time-critical hooks only temporarily.
		163
