[Haskell-cafe] Data constructors

I keep running into annoyance in having to name data constructors differently if they're for different types if they're in the same module or something. I wish that something like some Type.Constructor syntax worked in order to disambiguate. Or, better still, I have that problem with function names too (e.g. Data.List.union, Data.Set.union, IIRC) and it occurs to me that a lot of this can be resolved automatically because the types only make sense with one of the choices. I'm not really proposing any changes; more, I'm wondering what others' thinking is about this sort of thing - what annoys them, how they get around it, etc. -- Mark
