When implementing keyword argument support for Boost.Python, I noticed the
following. I'm sure it's not worth a lot of effort to change this behavior,
but I thought someone might like to know:

>>> class X:
...     def foo(self, y): print y
>>> X.foo(y = 1, self = X())
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: unbound method foo() must be called with X instance as first
argument (got nothing instead)
