So you can't do

>>> len(1,2) 2

a la list.append, socket.connect pre 2.0? (or was it 1.6?)

And don't forget the method-specific errormessage by passing ':len' in the format string. Of course, this can easily be (and probably should) done by passing another argument to whatever parses arguments in METH_O, rather than invoking string parsing magic every call.
