The issue here is that the wanteds are now sometimes not fully unflattened, isn't it?
No, the reported issue (in the Description) is that a Given `CFunEqCan` remains. I believe that all Wanted `CFunEqCans` are removed. It's inconsistent, I know, but hard to fix -- except by leaving the Wanted `CFunEqCans` too. Which might be useful for some... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15147#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
