#13998: Default Signature messes up arity of type constructor -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Yes: the visiblity of the `k` type parameter for `$dmeqForAllPoly` is somehow inconsistent with that of the class. See `Note [TyBinders and ArgFlags]` in `TyCoRep`. I have a fix in progress. As usual you have nailed the right place. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13998#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
