Failing to understand the oddities of the

[Mark Wieder]

I filed bug 10109 on this. It's open for comments and of course the rev team can
act on it or punt as they see fit. But I think it does need fixing. I can't see
any way now in which the current implementation makes sense, even as an
accidental side-effect. It's rather something to have to be aware of and
studiously avoid when coding. It would be nice to have One Less Pitfall, and I
don't see a downside to fixing it.
