New submission from Jeremiah Lowin:
If inspect.getcallargs() is called on a function and three or more arguments
are missing, an IndexError is raised instead of the expected TypeError.
This bug is present in Python 3.3 and 3.4.0 rc1 (5e05d7d3db9c). However, it
worked as expected in Python 2.7.6.
Example:
>>> import inspect
>>> def fn(a, b, c):
>>> pass
>>> inspect.getcallargs(fn)
Result:
IndexError: tuple index out of range
Expected:
TypeError: fn() missing 3 required positional arguments: 'a', 'b' and 'c'
