#12088: Type/data family instances in kind checking -------------------------------------+------------------------------------- Reporter: alexvieth | Owner: Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: #11348, #12239 | Differential Rev(s): Phab:D2272 Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): I really think this exactly the same problem. The crux of this ticket is
(type/data) instances can depend on other (type/data) instances so we have to get the order right.
#11348 goes some of the way to get the right order but doesn't account for dependencies between (type/data) instances. I am trying to write up these discussions on a wiki page as it is very messy currently. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12088#comment:22 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
