Exactly. Nothing has changed.

By the way, I didn't see any place the named return value optimization
could come into play, more likely the leaf/sibling routine optimization:
all the functions comprising the mis-compiled expression consist of
lone "return" statements creating temporary objects. But you must
know about this better...
