Hi, I am not sure if this has been mentioned before, but something I would really find useful is the ability to tell Haskell to export everything in a function except for some named functions. The problem at the moment is that if you have a large file with lots of functions and you want to export everything in that file apart from one function, then you have to either: export explicitly every function apart from the function you want; import the module hiding the function The first is time consuming and prone to errors and the second raises issues about making libraries portable. I may want to produce an API for example and not export a particular function for a particular reason - I don't want people who use my API to have to use import hiding every time they use it.
