Sorry, I'm a bit confused, as it seems to work for me with only __dict__
support, and built-in Python classes don't have a __methods__ attribute (at
least, not in Python 1.5.2):

>>> X
<class __main__.X at 84c898>
>>> x.__dict__
Traceback (innermost last):
  File "<stdin>", line 1, in ?
NameError: x
>>> X.__dict__
{'f': <function f at 84c848>, '__doc__': None, '__module__': '__main__'>}
>>> dir(X)
['__doc__', '__module__', 'f']
>>> X.__methods__
Traceback (innermost last):
  File "<stdin>", line 1, in ?
AttributeError: __methods__
>>> X().__methods__
Traceback (innermost last):
  File "<stdin>", line 1, in ?
AttributeError: __methods__
