Thanks Raphael, Wojciech and Anton. I tried out ide-haskell with the
ide-haskell-stack backend. Everything seems to be working well enough
to give it a go for my next project.

However, type-checking, linting and error display inside the editor is
far from real-time for me (never < 1s), but they never were for me, so
I don't think that has anything to do with Atom.
