I suppose so.  It's just that they create an additional exception cleanup
for new(ptr) expressions for no reason at all.  I've harbored thoughts of
raising the issue with the library WG, but have never gotten around to it.

Hmm.  Perhaps the purpose was to avoid calling some other placement delete
by mistake.

Ah, well.  I suppose the compiler could recognize their uselessness and
avoid the cleanup.
