#14332: Deriving clauses can have forall types -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.2.1 checker) | Resolution: | Keywords: deriving Operating System: Unknown/Multiple | Architecture: Type of failure: GHC accepts | Unknown/Multiple invalid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Why shouldn't we allow `forall` in deriving clauses? I agree that the current implementation is buggy (for example, that you need two sets of parens!), but I think `forall`s there are just peachy. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14332#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
