Starting next week I will start spending time on it to see what can be done.
George, how's it going? I've just noticed that in the compiler itself `PrelRules.hs` doesn't currently blow the limit, but the changes in [Phab:D2858] require `-fmax- pmcheck-iterations=6000000`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11822#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
