I wasn't necessarily proposing that the current behavior ought to be
changed. I hadn't considered all the subtle possibilities of such a change,
but in another msg suggested there would be some.

I suspect some people would disagree with you on this (that it's simply
complicating the interpreter to get rid of an avoidable problem - I don't
know what you meant about "notify a programmer"; I don't envision
notification if such a change were implemented).

Correct. My mistake.
I agree with you about all the other nasty corner cases.
