But you can't tell in a dtor whether you're being destroyed
deterministically or not.  The only safe assumption is that you aren't,
thus rendering dtors worse than useless.

All we'd need is a bool passed to a dtor to tell it whether it's being
destroyed deterministically or not and all will be rainbows and sunshine.

... except for the opDotExpr discussion.  Anyone who posts to that
thread is kuh-razy!
