Don't be discouraged; I think it would be useful. IMO, Haskellers tend to be pretty insensitive when it comes to usability.

For example, before the GHC devs were asked for that feature, I wonder whether anyone ever thought: "Hey, when ghc -Wall complains about having no type signature - why doesn't it print out the inferred type signature? That would be helpful and convenient."

I don't think it's because there's any sort of gung-ho elitism there, it's just not something anyone but the educators like the Helium folk really think about much.
