Hi Peter,

you're right... the code needed also other fixes and I didn't find a
way to do it other than this:

def foo(**kwargs):
    expected_form1_kwargs = ["arg1", "arg2"]

    for name in expected_form1_kwargs:
        if name not in kwargs:
            kwargs[name]=None

    for name in kwargs:
        if name in kwargs and name not in expected_form1_kwargs:
            raise ValueError, "Unrecognized keyword: " + name

    print kwargs
    
            
if __name__ == "__main__":
    foo(arg1=8)
