#15457: (~) and (!) are parsed inconsistently in types (plus documentation warts) -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.8.1 Component: Compiler | Version: 8.4.3 (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: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: patch => new * differential: Phab:D5023 => Comment: The approach in Phab:D5023 isn't quite up to snuff, since it leaves some scenarios where `!` isn't parsed in a precedence-aware fashion (see https://phabricator.haskell.org/D5023#139341). To handle that situation correctly, we'd need to implement something skin to the plan laid out in https://phabricator.haskell.org/D5023#139245. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15457#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
