#13140: Handle subtyping relation for roles in Backpack -------------------------------------+------------------------------------- Reporter: ezyang | Owner: ezyang Type: feature request | Status: patch Priority: normal | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Keywords: backpack hs- Resolution: | boot Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3123 Wiki Page: | -------------------------------------+------------------------------------- Comment (by ezyang): I'm not convinced the complexity is worth it. I think at least for GHC 8.2 we ought not to put in any of this, and we'll see if the role problems really cause people problems. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13140#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
