Hey, I like that. I'd let the default be an optional extra arg to the constructor: di = dict(int, default=0) di[key] += 1 without the setdefault. I might even add optional type checking: di = dict(int, default=0, typecheck=True) di[key] = 'foo' # raises TypeError -- http://mail.python.org/mailman/listinfo/python-list
