New submission from Jeremiah Lowin:
Tested in Python 3.3 and Python 3.4.0rc1 5e05d7d3db9c
If a function has keyword-only arguments but no keyword-only defaults, then
calling inspect.getcallargs with no arguments results in the wrong TypeError
being raised.
Example:
>>> import inspect
>>> def fn(*, a):
>>> pass
>>> inspect.getcallargs(fn)
Result:
TypeError: argument of type 'NoneType' is not iterable
Expected Result:
TypeError: fn() missing 1 required keyword-only argument: 'a'
