[Nix-dev] Switch to GHC 7.10.1 is imminent

[Peter Simons]

Fellow Haskellers,

I'd like to merge https://github.com/NixOS/nixpkgs/pull/7037 soon, i.e.
by the end of this weekend. This means that haskellngPackages will point
to the "haskell-ng.packages.ghc7101" package set henceforth. You can see
the current state of what compiles and what does not at
http://hydra.cryp.to/jobset/nixpkgs/haskell-updates-ghc7101. If you feel
that this switch is a bad idea and that we should postpone the update,
then please make your voice heard on the Github issue tracker or on this
mailing list.

Best regards,
Peter
