		95	=head2 Extension Objects
		96
		97	Every perl extension is a perl class. A separate perl object is created
		98	for each terminal, and each terminal has its own set of extension objects,
		99	which are passed as the first parameter to hooks. So extensions can use
		100	their C<$self> object without having to think about clashes with other
		101	extensions or other terminals, with the exception of methods and members
		102	that begin with an underscore character C<_>: these are reserved for
		103	internal use.
		104
		105	Although it isn't a C<urxvt::term> object, you can call all methods of the
		106	C<urxvt::term> class on this object.
		107
		108	It has the following methods and data members:
		109

		115	extension. This member I<must not> be changed in any way.
		116
		117	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		118
		119	Dynamically enable the given hooks (named without the C<on_> prefix) for
		120	this extension, replacing any previous hook. This is useful when you want
		121	to overwrite time-critical hooks only temporarily.
		122
