If it used keywords then you could keep symmetry quite easily:
def anyargs(arglist args, argdict kwargs):
return wrappedfunc(arglist args, argdict kwargs)
and you would have the advantage of two new keywords that people could
actually search on.

Irrelevant, you can't subclass both list and dict:
>>> class C(list, dict): pass
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
class C(list, dict): pass
TypeError: multiple bases have instance lay-out conflict
