A long long time ago, Hal Daume III made Haskell All-in-one which takes a 
Haskell program and puts all the modules into one file.  The difference in 
efficiency was discussed on one of these mailinglists then.  Google should be 
able to turn up something (albeit it seems to no longer index the haskell.org 
mailinglists directly).
