#15351: QuantifiedConstraints ignore FunctionalDependencies -------------------------------------+------------------------------------- Reporter: aaronvargo | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.5 checker) | Keywords: Resolution: | QuantifiedConstraints Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AntC): Your constraint for `bar` doesn't look well-formed to me. I'm surprised GHC accepted the `forall` without an implication `=>`. I guess what you've ended up with is some sort of impredication. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15351#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
