To add to what others have said, you might want to read the Simons' paper "Secrets of the Glasgow Haskell Compiler Inliner": http://research.microsoft.com/~simonpj/Papers/inlining/ It's pretty accessible, and talks about the various knobs that can be twiddled in order to influence the black art of inlining.
