Well, I don't mean the compiler should guarantee that my code will be optimized
in a certain way, but it's handy to be able to verify that it _qualifies_ for
those optimizations.

That said, I think my suggestion is a minor convenience feature, and is much,
much less important than ironing out the design/implementation issues that
others have raised in this thread.
