While I'm here, can I just clarify *exactly* what -funbox-strict-fields actually does?
If in doubt, ask the user's guide:
http://www.haskell.org/ghc/docs/latest/html/users_guide/pragmas.html#unpack-...
...so making a field strict causes it to be automatically forced when the constructor is forced, but doesn't actually unbox it? So there's still a level of indirection, and no register allocation?
