#14086: Empty case does not detect kinds -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: low | Milestone: 8.4.1 Component: Compiler (Type | Version: 8.2.1 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * cc: RyanGlScott (added) Comment: I'm somewhat surprised this doesn't work, given that `Type` expands to `TYPE LiftedRep`, and `TYPE` is itself a datatype with no constructors. Granted, it is a somewhat magical datatype, but perhaps that just means we need to adjust the magicks appropriately for the `EmptyCase` pattern-match exhaustivity checker's purposes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14086#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
