I'll take a look at the zip function, didn't know about that one, but
your example also has the problem that dictionaries can't be used as
dictionary keys, but that can be easily solved. I think I can simplify
my solution with some of yours.
The parameter names can be gotten by doing a inspect.getargspec(fn)[0]
so that can be done by the decorator function.
