I agree this should be a FAQ.
we already have something like this on performance/strictness wikipage. although adding your example of misusing $! may be helpful - peoples are always better learned on (good and bad) examples rather on bare theory
Perhaps I should write it up for the performance section of the wiki? Looking back I see my mental error was that I thought I was doing what you and everyone else correctly suggested:
writeSTRef (state t) $! nextState s
but what I actually typed was
writeSTRef (state t) (nextState $! s)
which of course doesn't help. Another telling example of the fact that coffee is not an entirely adequate substitute for sleep.
