#15905: Data familes should end in Type -------------------------------------+------------------------------------- Reporter: simonpj | 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: #14645 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Ah yes. Not quite a duplicate of #14420, but it would nail #14420 inter alia. In particular, the description of #14420 says (a bit impreciseely) "We should require that any instantiation of a data family be to a kind that ends in Type." My proposal in this ticket would make that true automatically, because data family kinds would always end in Type, and hence a fortiori so would their instantiations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15905#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
