#14819: GHC 8.2 does not accept British {-# LANGUAGE GeneralisedNewtypeDeriving #-} spelling -------------------------------------+------------------------------------- Reporter: clinton | Owner: (none) Type: bug | Status: new Priority: lowest | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: 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 osa1): Happens in HEAD too. Looking at `DynFlags` at the time when `-XGeneralisedNewtypeDeriving` added, I think this version of the flag was never supported. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14819#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
