[Haskell-cafe] about integer and float operations

I think you mean that if you have
        module M(f) where
          f = ...
          g = ...

precompiled in a library, is it possible to call g?

No, I'm afraid it isn't, at least in GHC. For example,  'g' may no longer exist... it may have been inlined into 'f'.
