#15869: Discrepancy between seemingly equivalent type synonym and type family -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.6.2 checker) | Keywords: TypeFamilies, Resolution: | TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): It's entirely possible that (2) is actually a duplicate of #14319, especially in light of comment:8. (Then again, it's not clear why `KindOf2 A` isn't reducing in that type family equation in the first place—see comment:9.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15869#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
