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

132	object that is shared between all packages is stored in the C<term>
133	member. It is, however, blessed intot he package of the extension script,
134	so for all practical purposes you can treat an extension script as a class.
