Hi,

was there a change in how GHC simplifies instances sometime between
7.4.1 and 7.6.1? Haddock used to produce this:

  http://hackage.haskell.org/packages/archive/kan-extensions/2.7/doc/html/Data-Functor-Yoneda.html

but is now producing this:

  http://hackage.haskell.org/packages/archive/kan-extensions/3.1/doc/html/Data-Functor-Yoneda.html

Haddock uses tcRnGetInfo to get the instances.

Thanks,
David
