#14048: Data instances of kind Constraint -------------------------------------+------------------------------------- Reporter: Iceland_jack | 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: #12369 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): This is a larger feature request than just a relaxation of kind checking. It requires, e. g. the syntax for declaring a class instance for a data family. I think this is a large enough delta on the current intentions for data families that it should properly be a ghc-proposal. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14048#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
