#13990: Core Lint error on empty case -------------------------------------+------------------------------------- Reporter: mbieleck | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1-rc3 Resolution: | Keywords: core-lint | case Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): A `Coercion` exhibits a property of a type (equal to another type). What you want is a witness of a property of a *value* – quite similar to the “value coercions” that we phantasized a few months ago. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13990#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
