		155
		156	Very perl extension is a perl class. A separate perl object is created
		157	for each terminal and each extension and passed as the first parameter to
		158	hooks. So extensions can use their C<$self> object without having to think
		159	about other extensions, with the exception of methods and members that
		160	begin with an underscore character C<_>: these are reserved for internal
		161	use.
		162
		163	Although it isn't a C<urxvt::term> object, you can call all methods of the
		164	C<urxvt::term> class on this object.
