#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 RyanGlScott): Just as well, perhaps the `k` in `$dmeqForallPoly` shouldn't be available for visible type application in the first place. Indeed, the code which generates `Main.$dmeqForallPoly @(Main.Value)` already [http://git.haskell.org/ghc.git/blob/d7b17517e26007f537feab490509c0e13e0e239a... filters out] invisible type arguments, but it seems that the `k` in `$dmeqForallPoly` isn't properly marked as invisible. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13998#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
