Instances visible in various Haskell modules

• Haskell implementation: ghc-7.8.4
• All other packages: LTS Haskell 2.3 from Stackage
• Calculated using the code at https://github.com/skilpat/class-struggle

import ReadWorlds
ctx <- buildCtx "<cabal-sandbox-path>" ["base", "containers"]
printCtx ["Prelude", "Data.Map"] ctx

• Format:
