[Nix-dev] Should we switch the default Haskell compiler to GHC 7.4.2?

[Peter Simons]

Hi guys,

the default 'haskellPackages' attribute is based on GHC 7.4.1, which is
the version recommended by the latest Haskell Platform. However, GHC
7.4.2 was released a while ago, and IMHO that version is just as stable
as 7.4.1 -- if not more --, so I would like to switch our default choice
of the compiler to the later version.

Would anyone object that change?

Take care,
Peter
