New submission from Milko Krachounov <pyt...@milko.3mhz.net>:
If I make a class B, and add staticmethod(A) as an attribute when B is another
class, help(B) breaks. The issue appears with Python 2.6.6, trunk, 3.1.3c1, and
py3k SVN.
Python 2.7 (trunk:86836, Nov 27 2010, 18:23:07)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class A(object):
... pass
...
>>> class B(object):
... attr = staticmethod(A)
...
>>> help(B)
