'inspect.getargspec()' will get you the names of the positional
arguments for the class's __init__ method. You can then work through
the positional values in your __call__'s *args, matching a name to each.
Assuming you have those argument names stashed away somewhere, maybe
something like:
def __call__(self, *args, **kw):
for i, value in enumerate(args):
kw[self.names[i]] = value
# everything is now in kw
