115 Extension Objects
116 Very perl extension is a perl class. A separate perl object is created
117 for each terminal and each extension and passed as the first parameter
118 to hooks. So extensions can use their $self object without having to
119 think about other extensions, with the exception of methods and members
120 that begin with an underscore character "_": these are reserved for
121 internal use.
122
123 Although it isn't a "urxvt::term" object, you can call all methods of
124 the "urxvt::term" class on this object.
125
126 It has the following methods and data members:
127
128 $urxvt_term = $self->{term}
129 Returns the "urxvt::term" object associated with this instance of
130 the extension. This member *must not* be changed in any way.
131
132 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
133 Dynamically enable the given hooks (named without the "on_" prefix)
134 for this extension, replacing any previous hook. This is useful when
135 you want to overwrite time-critical hooks only temporarily.
136
137 $self->disable ($hook_name[, $hook_name..])
138 Dynamically disable the given hooks.

106 and extension package. You can call all "urxvt::term" methods on it, but 145 the in the "Extension Objects" section.
107 its not a real "urxvt::term" object. Instead, the real "urxvt::term"
108 object that is shared between all packages is stored in the "term"
109 member. It is, however, blessed intot he package of the extension
110 script, so for all practical purposes you can treat an extension script
111 as a class.
