#13833: Instances with GHC.TypeLits.Nat/Symbol should be possible without FlexibleInstances. -------------------------------------+------------------------------------- Reporter: Hjulle | Owner: (none) Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 8.0.2 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AntC): Um, is there anybody using fancy type stuff like `TypeLits`, but not needing `FlexibleInstances`? I know [https://downloads.haskell.org/~ghc/8.4.2/docs/html/users_guide/glasgow_exts.... `-fglasgow-exts`] is deprecated these days, but I always switch on those extensions anyway. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13833#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
