Yep.  You just need to make the first parameter of your method 'self', and
not have any parameters with default values.  For example, method plusX::

  <params>self, x</params>
  return len(self.objectIds()) + x

...can be called like 'folder.plusX(3)'.  You can also acquire objects that
your method needs from 'self'.
