[Haskell-beginners] Load functions from broken source code files?

Is there some way in GHCi to load a single function from a broken source code file? E.g, you're writing a program, the main function is incomplete, and half the other functions are broken, but you are developing one function and you just want to load in the current version of that, reload it after some editing, and so forth. I can see how normally that would not be a good idea, but I was wondering if there was some hackish way to do it that was fairly easy and quick. -- frigidcode.com theologia.indicium.us
