"stack ghci" should either use haskell2010, or pay attention to the cabal file language specification #2092

From nitrix on #haskell, line 15 of http://lpaste.net/162186 has a do block with the contents aligned with the let. It builds with haskell98 but not haskell2010.

Actually, it compiles with stack ghci but not with stack build. The error says Parse error on a binding <- of a do block. (line #15 on the paste). The project is indeed haskell2010; we suspect it could be the issue.

Right, stack ghci is running in haskel98 mode. stack build knows to use haskell2010.
