Not sure if it quite counts as "existing code", but I do often use
this notation during development to indicate that this class will
exist, but I haven't coded it yet. (In contrast, "class C: pass"
indicates that an empty body is sufficient for this class, eg "class
SpamException(Exception): pass" which needs no further work.)
If a less subtle distinction is needed, what about "class C = None"?
That removes the expectation of a colon and body. Personally, I'm
still inclined towards the kwarg method, though ("class
C(forward=True): pass"), since it's legal syntax.
