But it's really a bit radical to make this kind of out-of-spec promotion by default. Would you rather put them under options? After all, these conversions are very clever.

I continue to think they want doing by default, with possibly a way to turn
them off (compiler mode) and/or diagnose them (perhaps no more than "info"
level).
