Consider the following example.

    import inspect
    inspect.getcallargs(lambda **kwargs: None, func=1)

IMHO `getcallargs` should return

    {'kwargs': {'func': 1}}

however, Python (versions 3.3 and 3.4) throws the following exception instead:

    TypeError: getcallargs() got multiple values for argument 'func'

This can be easily solved in `lib/` by changing

    def getcallargs(func, *positional, **named):


    def getcallargs(*func_and_positional, **named):
        func, *positional = func_and_positional

Best regards,
