Re: [Haskell-cafe] Operational Semantics of Haskell

Hi

Is there a good source for the operational semantics of Haskell? I am trying to squeeze the most efficiency out of a bit of code and am looking to remove unnecessary reductions.

You probably aren't after operational semantics - the compiler takes your code and optimises it to something bearing little relation to the original. Are you passing -O2? Have you read the performance wiki page? http://haskell.org/haskellwiki/Performance Thanks Neil
