... and erm, how can I enable parsing of optimizer rules? With {-# OPTIONS_GHC -O #-} ?
Yes, although note that Cabal passes -O by default. I'd recommend not putting it in a pragma, as that will break ./Setup configure --disable-optimization
I think the question was how to get the RULES pragmas to be parsed. One does have to turn on a language extension to get the forall in rules to parse and it's not very clear at the moment which one we should be using. See http://hackage.haskell.org/trac/ghc/ticket/2497 Duncan
