Interesting survey results, specifically that it seems that:

users of the language are generally happy with it and its compiler
few are using Haskell at their work, but more would like to
package management is the thing that everyone is least happy with

Actually, going to quote that last one directly:

Package management with cabal is the single worst aspect of using Haskell. Asked if improvements to package management would make a difference to their future choice of Haskell for a project, 38% said it would be "crucial" and a further 29% said it would be "important". Comments connected cabal with words like hell, pain, awful, sucks, frustrating, and hideous. Only this topic showed such grave dissatisfaction.

I suspect those feelings with Cabal are hardly a Cabal-only situation, or even Cabal's fault. Other language packaging also seems bad, but there's clearly a void that language package managers are filling. But is language package management really the right way to fill that void?

Even more can be said on that subject, for another time. Still, interesting!
