#16311: Suggest -XExistentialQuantification for 'forall' in data declarations -------------------------------------+------------------------------------- Reporter: int-index | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 (Parser) | Resolution: | Keywords: 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 int-index):
Do we need both? Or is there a way we could consolidate the two somehow? Would the answer change if we made forall permanently a keyword in types?
No, we don't need both, and the `forall` proposal makes the matters trivial. See https://gitlab.haskell.org/ghc/ghc/merge_requests/363 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16311#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
