#14331: Overzealous free-floating kind check causes deriving clause to be rejected -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: merge Priority: normal | Milestone: 8.2.2 Component: Compiler (Type | Version: 8.2.1 checker) | Resolution: | Keywords: deriving Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | deriving/should_compile/T14331 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): You're right that the user could specify this, but I see the original `deriving` as ambiguous -- only we don't report it as so. Worth fixing? I'm not sure. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14331#comment:22 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
