[IronPython] abstract base classes

[Dino Viehland]

I didn't even realize this is broken.  Probably 2.6.2 at the earliest - it looks like we had the test case which validates this disabled due to a generic "needs to work on 2.6 bug".

I've opened this more specific bug: http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26499

Thanks for the report!

Subject: [IronPython] abstract base classes

This is probably something well known, but I just tried using ABCs in IPy 2.6 for first time and saw that they don't enforce anything:

from abc import ABCMeta, abstractmethod
class A(object):
    __metaclass__ = ABCMeta

    @abstractmethod
    def foo(self, x):
        pass

class B(A): pass # no foo method

b = B() # shouldn't work, but does


Do you know if/when this is planned to be fixed?

thanks
Ronnie
