DataKinds and package boundaries: "the 'impossible' happened"
I don't know what is going on there, so I can't really give much more information, sorry.
aristid@sigmoid:~/Code/aws/Examples$ ghc -package-conf ../dist/package.conf.inplace GetObject.hs
[1 of 1] Compiling Main ( GetObject.hs, GetObject.o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.4.2 for x86_64-unknown-linux):
tyThingTyCon
Data constructor `aws-0.7.0:Aws.Core.NormalQuery{d r2qt}'
