#14921: Type inference breaks on constraint-kinded parameter used by a Rank-2 callback -------------------------------------+------------------------------------- Reporter: glittershark | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: #10651, #15649 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: new => closed * resolution: => invalid * related: #10651 => #10651, #15649 Comment: I'm going to close this, since the fact that this program doesn't typecheck is expected behavior (at least, according to the specification in the OutsideIn(X) paper, as explained in https://ghc.haskell.org/trac/ghc/ticket/10651#comment:2). See also #10651 and #15649, which are similar tickets. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14921#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
