		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.

		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.
