I don't really understand what you are trying to do, but you are
invited to check out xapply.py in my bytecodehacks package which can
be found at

http://starship.python.net/crew/mwh/

and is documented here:

http://starship.python.net/crew/mwh/bch/module-bytecodehacks.xapply.html

If that isn't what you're after, can you post an example of what you
might want to do with this hypothetical function? I can probably whip
something up for you.

Cheers,
Michael
