#15379: Don't reject user-written instances of KnownNat and friends in hsig files -------------------------------------+------------------------------------- Reporter: ezyang | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | Keywords: backpack Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ppk): I have started working on this bug at <https://github.com/piyush- kurur/ghc/tree/literal-instac>. Not yet on phab because I am waiting for the fix of #15138 to get merged. Will rebase and send the patches then. But here is a status report of what I have done 1. Added a testcase 2. Made the minimal modification that we discussed over IRC Unfortunately just 2 does not help as there is a overlapping instance error that is being thrown. I will investigate this and let you known. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15379#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
