Everybody has already explained why this doesn't work and a possible
"solution" using metaclasses was suggested. I tried to implement it,
ended up with monkey-patching __bases__, which is certainly an
abomination (will it be possible in python 3.0?) but seems to do the
trick.

This is not true.
Human beings have extremely shallow mental stacks, limited by short-term
memory. Most people are c

Use metaclasses?

Sorry - code for the class should read:
class Tree(object):
...class _MT(Tree):
..def isEmpty(self): return True
..def insert(self, X): return Tree._Node(X)
...class _Node(Tree):
..def isEmpty(self): return False
..def insert(self, X): return _Node(X, self, Tree._MT())
...def __ini
I want - but cannot get - a nested class to inherit from an outer
class. (I searched the newsgroup and the web for this, couldn't find
anything - if I missed an answer to this please let me know!)
I would like to build a class for a data structure such that nodes of
the data structure - of intere
