		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	Additional methods only supported for extension objects are described in
		109	the C<urxvt::extension> section below.

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