And unsafeRead/unsafeWrite are too verbose. They are usually (almost
always?) safe (since the code does its own checks), so perhaps this
essential-for-performance interface should have nicer names?
They're not in the same unsafe league that unsafePerformIO is. Just
something I pondered during the shootout massacre a couple of weeks
