I tried doing the "standard" worker/wrapper transform to some functions in Data.Map. For example, by transforming

insertWithKey' f kx x t0 = kx `seq` go t0 where go t = case t of
I got a 16% speedup on this benchmark:
Looks like as well as W/W you've also made it strict in the key, so this speedup isn't all W/W. Thanks Ian
