Comment(by mikhail.vorozhtsov): Replying to [comment:1 simonmar]: > Is this a regression? Probably no. If I remove the equality superclass "l ~ (HHead l :* HTail l)" from the HNonEmpty class declaration the panic goes away. Equality constraints in class contexts were implemented just recently. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5315#comment:2> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
