Does this help?

>>> def spam(a, b, c=3, d=4):
...     pass
...
>>> spam.__code__.co_varnames
('a', 'b', 'c', 'd')

The hardest part is having the function know its own name.

I see that you are already using the inspect module. That almost 
certainly is the correct approach. I'd be surprised if inspect is too 
heavyweight, but if it is, you can pull out the bits you need into your 
own function.
