It's not the literal syntax you're asking for, but using my technique
for multiple dispatch in Python achieves the effect you're looking
for. It has nothing to do with metaclass, but it lets you provide
multiple "signatures" for a call. Not just number of arguments, but
also their types (if you want: you can also generically specify a
descendent of object).
