[GHC] #11267: Can't parse type with kind ascription with GHCi's :kind command
#11267: Can't parse type with kind ascription with GHCi's :kind command -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.10.3 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: -------------------------------------+------------------------------------- I was playing around with GHCi's `:kind` command and noticed that trying to ascribe a type with a kind doesn't parse: {{{ $ inplace/bin/ghc-stage2 --interactive GHCi, version 7.11.20151219: http://www.haskell.org/ghc/ :? for help λ> :set -XTypeInType λ> :kind 'True :: Bool <interactive>:1:7: error: parse error on input ‘::’ }}} This seems like something that should be able to parse, given that `:type True :: Bool` parses just fine. Is there a reason it couldn't? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11267 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Not sure precisely why, but I'm sure that the parser would be made more complicated by relaxing this restriction. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11267#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
