Also, as a bit of a teaser, I think Richard Smith is going to be looking
into providing much more extensive optional *checking* of undefined
behavior. Essentially, '-fcatch-undefined-behavior' may grow some serious
teeth. This should allow users to check their code fairly aggressively for
UB but not needlessly punish code or those debugging code.
