I have experienced cases where simply recompiling with a new GHC speeds up my program 5x. I've also experienced cases where I had to take perfectly readable code and turn it into something ugly--but not to the extent that it is done in the Haskell code on the language shootout. I would prefer to have the language shootout revert back to idiomatic versions of the programs, and then look at how we can optimize those idiomatic programs automatically in the same way that good SQL implementations optimize SQL queries.
