You don't need all that machinery tho, something simpler like:
def command(func, *args, **kw):
def _wrapper(*wargs):
return func(*(wargs + args), **kw)
return _wrapper
would work too. But considering that code is using "apply", I will
take it as really old and outdated by now.
Ooo. Much better. I got mine from Grayson's book which says it
originally came from a Tim Evans post to the Python newsgroup.
Thanks!
