I just wanted to make a feature request to ghc --make (there seem to have been a number of such...) I have a project currently consisting of 36 Haskell modules, and a number of support modules for those. Naturally, compiling this takes quite some time (even for ghc --make) especially considering that one of the modules is a happy-generated parser. When I make a bug fix in one of the modules early in the dependancy chain, this forces a recompile of all the modules above it, even if the modules interface hasn't changed. I would suggest that when ghc --make recompiles a module, it should compare the new interface with the old one, and if they are the same, doesn't force recompiliation of the modules that depend on it, but merely change the time on those files without actually compiling.
