A friend at work who is new to Python wondered why this didn't work with pickle:

class Outer: Class Inner: ... def init(self): self.i = Outer.Inner() I explained:

http://docs.python.org/library/pickle.html#what-can-be-pickled-and-unpickled

From that: # functions defined at the top level of a module # built-in functions defined at the top level of a module # classes that are defined at the top level of a module I've never questions this, but I wonder, is this a fundamental restriction or could it be overcome with a modest amount of work?

This is related to http://bugs.python.org/issue633930
