The best way to author haskell yet

Editing haskell code is a pain in the ass.

The issue

There isn't a good IDE for haskell which can help you learn all the possibilities of the language by advising better solutions to a specific problem.
On the other side if you choose to use a text editor (Sublime) you'll write several lines of code just to get hilarious compiler errors like:

Could not deduce (b ~ a)  
from the context (Eq a, Eq b)  

What?

Luckily github released its new, revolutionary text editor last week:

The solution

Atom Text Editor + Haskell IDE package

Just download the Editor from their website and install the packages following packages using File > Settings > + Install
- language-haskell - haskell-ghc-mod - ide-haskell - autocomplete-haskell

The fast way:

$ apm install language-haskell haskell-ghc-mod ide-haskell autocomplete-haskell
