i propose you to use INLINE pragma:{-# INLINE foo #-} unless your function is recursive. in this case, you should use SPECIALIZE pragma: {-# SPECIALIZE foo :: Double -> Double -> Double #-}
I suggest *not* using these pragmas unless a combination of profiling and reading intermediate code dumps suggests that foo -- and its un-specialized nature -- is truly a bottleneck. Excessive amounts of SPECIALIZE pragmas can make your code ugly without actually improving performance if you optimize prematurely (and I speak from experience). Think *first*, add pragmas later; again, people on the mailing lists and IRC channel are usually happy to provide guidance with this.
