Comment (by dherington):
It seems what you want is already provided (unless I misunderstand):
bash-3.2$ cat Test.hs
top :: Int -> Int
top x = mult 4 - mult 3 + mult 2
where
mult n = x * n
bash-3.2$ ghci Test.hs
GHCi, version 6.10.3: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer ... linking ... done.
