 When I try to compile tests provided in the
 [http://hackage.haskell.org/package/singletons singletons] package I get
 the following error:

 {{{

 }}}

 This happens on HEAD but not on 7.6.3. Steps to reproduce:

 1. Download and extract singletons source code
 2. In the cabal file uncomment test-suite section (which is commented out
 because it doesn't work)
 3. `cabal configure --enable-tests && cabal build`

 Reproducing this requires installing packages required by singletons. I'm
 setting milestone to 7.8 as this is something that looks like a blocker in
 a stable release.
