commit 37bd95fee83b50c2567914a6e6c2a4cc73803f30
Author: Matthew Pickering <matthewtpickering at gmail.com>
Date:   Wed Feb 28 18:09:34 2018 +0000

    Pin nixpkgs and all-cabal-hashes in shell.nix (#511)
    
    * Pin shell.nix
    
    Also adds a new option to build `cabal-install` HEAD which is
    sometimes useful.
    
    * Bump QuickCheck bound
    
    * Remove cabal-install which snuck in
