Meta-class inheritance problem (Python2.0 bug?)

[Lorien Dunn]

Hullo all,
        I've been using boost::python for a little while now- long enough to have 
seemingly successfully wrapped my extension, and I've run into a bug in 
python 2.0. The real code that the following pseudo code represents throws 
a TypeError. 

class MyDerivedClass(MyPurePythonClass, MyBoostClass): 
        def __init__(self):
                MyPurePythonClass.__init__(self)
                MyBoostClass.__init__(self)

The problem occurs in MyPurePythonClass- Python says "unbound method must 
be called with class instance 1st argument". This makes sense: I'm passing 
a meta-class instead of a class. David Abrahams (the main author of 
boost::python) agrees that this is a Python problem, and that it should 
affect Zope as well.

He also said that it should be an easy modification, but he doesn't know 
what ramifications it would have throughout the rest of the python 
interpreter.

Advice anyone?

Thanks,
Lorien Dunn
