209<p>Very perl extension is a perl class. A separate perl object is created
210for each terminal and each extension and passed as the first parameter to
211hooks. So extensions can use their <code>$self</code> object without having to think
212about other extensions, with the exception of methods and members that
213begin with an underscore character <code>_</code>: these are reserved for internal
214use.</p>
215<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
216<code>urxvt::term</code> class on this object.</p>
