--- Comment #3 from Aryeh Gregor <ayg at aryeh dot name> 2012-07-31 16:18:14 UTC --- Yeah, sorry, it was a bad example. Assigning 72 to this enum is undefined, so maybe this behavior is justifiable. The real-world example I was looking at didn't have that issue, though -- feel free to use A = 72 or something if you like.
