Hi Tim, I've gone ahead and cooked up a tiny demo patch that uses im_class to store what you called im_type. Because I don't have the parser changes ready yet, this requires you to declare a keyword-only arg named 'super'; this triggers special code that set it to super(im_class, im_self).
http://python.org/sf/1727209 I haven't tried to discover yet how much breaks due to the change of semantics for im_class. --Guido On 5/27/07, Guido van Rossum <[EMAIL PROTECTED]> wrote: > On 5/27/07, Tim Delaney <[EMAIL PROTECTED]> wrote: > > Guido van Rossum wrote: > > > > > The bound method object isn't stored in the class -- it's created by > > > the "C.method" or "inst.method" getattr operation.
