It shows GHC optimizer at its best, with at least 10-20% improvement in every major version of the compiler since 6.12. Unfortunately at cost of very long compile times. Please let me know if I should submit a driver code for automatic benchmarks it (it is in hPDB-examples.)

And #8960, where GHC runs out of memory. (Only in 7.8.) Should be easy to reproduce by just `cabal install hPDB`. >> > I notice that the latter three are actually fixed in 7.8, so worth trying >> > that.

That should get you going. -- Best regards Michal
