#11424: "Occurs check" not considered when reducing closed type families -------------------------------------+------------------------------------- Reporter: diatchki | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: 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 goldfire): Yes. I think we're vigorously agreeing. Except that this is quite far from the way GHC works at the moment, and it's not a small change to make. I do think it's the right answer, in the end. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11424#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
