It's easy to implement - here's a proof-of-concept in Python code that would
do it, using the way func._slots is a list of 'void func(type)',
'void<lambda>(type)', 'void func(type,type2,type3)' strings.
class Signal:
def __getitem__(self, item):
pass # that's already sorted out, it returns some object with a
connect method
def connect(self, func):
if hasattr(func, '_slots'): # decorated with Slot
for signature in func._slots:
self[signature.split('(')[1][:-1]].connect(func)
else: pass # raise exception, guess no arguments or whatever.
(Note this skips checking if the slot's signatures are valid for the signal;
I couldn't find how a signal lists the signatures it supports.)
This is just a proof of concept, but I think it should show that it's not
really a problem implementing it. signal.connect and signal[...].connect
can be completely different.

(I hope I'm not being a pest? I don't think I have anything else to say on
this point, anyway. But I do like to try and get PySide as Pythonic as
possible and am very happy with the way it's progressing.)
