That's quite an analysis, one I'll keep for future reference.
So, my original coding was the fastest. Guess I should stop second guessing myself. ;-)
I think Bas's point was actually that you should second guess yourself and use Criterion/ghc-core if you want to know which way is fastest. On the other hand, these are microbrenchmarks and should not be taken as representative of how they will perform inside a larger application.
Evidence is always nice to have :)
