Believe me, it is. Have a look at my `self.super` recipe at: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/286195 and the considerably faster Pyrex version at: http://members.optusnet.com.au/tcdelaney/python.html#autosuper I'm sure there are some edge cases which are not covered by the implementation, but it gets the vast majority of them. And I haven't tested it with Jython or IronPython. It works using sys._getframe() (to get the code object and method name), then walks the MRO to find which class has a method with the same name and code object (there's a bit more to it to prevent recursion). `self.super` is also callable - if you call `self.super(params)` it invokes the method on the superclass with the same name as the current method.
