Is it ? I didn't see any messages on the list saying that the idea is dead -- only that a PEP is needed and that it cannot be done for 2.2.

I'd like to move forward with the isinstance(x, (A, B, C...)) patch.

Followup question: should I also implement issubclass(X, (A, B, C...))? It's consistent to do so, but it's more work (issubclass is a bit murkier due to the "abstract subclass" support), and I'm not sure that it has the same benefits...
