What Haskell users are actively maintaining or deving software using ghc <8

[Andreas Abel]

I am using ghc 7.6 and up.  I dropped support for ghc 7.4 and below 
because I fancy

   \case

which is new in 7.6.

I'd say there is little reason to support ghc 6 any longer (but probably 
this is anyway the consensus).

That said, I do not maintain any libraries.  Libraries should not drop 
ghc versions lightly.
