145=head2 Extension Objects
146
147Very perl extension is a perl class. A separate perl object is created
148for each terminal and each extension and passed as the first parameter to
149hooks. So extensions can use their C<$self> object without having to think
150about other extensions, with the exception of methods and members that
151begin with an underscore character C<_>: these are reserved for internal
152use.
153
154Although it isn't a C<urxvt::term> object, you can call all methods of the
155C<urxvt::term> class on this object.
156
157It has the following methods and data members:
158

164extension. This member I<must not> be changed in any way.
165
166=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
167
168Dynamically enable the given hooks (named without the C<on_> prefix) for
169this extension, replacing any previous hook. This is useful when you want
170to overwrite time-critical hooks only temporarily.

137object that is shared between all packages is stored in the C<term>
138member. It is, however, blessed intot he package of the extension script,
