Hmm... now that I've been reminded of this bug, I might as well try to revive it.
I think my question has more to do with the granularity of well-defined-ness. 
Consider the expression A + (B,C), which contains a subexpression (B,C) which is
itself an expression.  If the expression (B,C) does not contain conflicts,
should not its behavior be well-defined?  Should not the A-B/A-C conflict in the
outer expression mean only that the outer expression's behavior be undefined,
and not affect the well-defined-ness of the inner expression?
