[Haskell-beginners] auto set objects imported

Hey, It seems to be good practice, to explicitly say, which objects one wants to import in an import statement: import SomeModule (someFunc) while this is good documentation, it can be cumbersome to maintain. So I was wondering: Is there some tool, that automaticly finds out which functions I use from which module and modifies my import statements? That would be most usefull! Regards, Nathan
