BTW a switch in a class should be treated the same as a global switch. But what about a switch in a class in a function? Okay, now my head hurts. :) A switch in a class doesn't need to be treated the same as a global switch, because locals()!=globals() in that case. I think the top-level is the only thing that really needs a special case vs. the general "error if you use a local variable in the expression" rule. Actually, it might be simpler just to always reject local variables -- even at the top-level -- and be done with it.

I don't get what the problem is here. A switch constant should have exactly the bahavior of a default value of a function parameter. We don't seem to have too many problems defining functions at the module level, do we?
