#10194: Shouldn't this require ImpredicativeTypes? -------------------------------------+------------------------------------- Reporter: kosmikus | Owner: Type: bug | Status: merge Priority: normal | Milestone: 7.10.2 Component: Compiler (Type | Version: 7.8.4 checker) | Keywords: Resolution: fixed | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: GHC accepts | Test Case: invalid program | typecheck/should_fail/T10194 Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by adamgundry): @refold can you be more specific about what breaks? One would expect some programs that were previously (erroneously) accepted to now require `-XImpredicativeTypes`. That's not necessarily a reason to revert this patch. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10194#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
