#13267: Constraint synonym instances -------------------------------------+------------------------------------- Reporter: ezyang | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC accepts | Test Case: invalid program | polykinds/T13267 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): Certainly, since `Typeable1` is a constraint synonym for `Typeable` (since the 7.8 release, where `Typeable` became poly-kinded). But `Typeable1`, `Typeable2`, //et al.// have also been deprecated since 7.8 - surely you can just use `Typeable` instead? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13267#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
