#16024: Kind Signatures on data instances -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 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 goldfire): This has nothing to do with data instances. Datatype declarations that use `=` cannot also have a kind signature; only GADT-syntax declarations can have a kind signature. An empty datatype is considered to be in GADT syntax. So the bug here essentially just a thinko in that comment. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16024#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
