#10085: Type families cause wrapper types to disappear without cause -------------------------------------+------------------------------------- Reporter: tathougies | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 7.8.3 checker) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | Blocking: Blocked By: | Differential Revisions: Related Tickets: | -------------------------------------+------------------------------------- Comment (by glguy): There may be other issues here, but a significant one is that you're partially applying a type synonym family. This check was missing in 7.8 but is fixed for 7.10 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10085#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
