#15284: Can't parse ''(*) in GHC HEAD -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 (Parser) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I can't build the `reflection` library on GHC HEAD since the `''(*)` Template Haskell name no longer parses. Here is a smaller example which compares GHC 8.4.3 (what should happens) with HEAD (which fails): {{{ $ /opt/ghc/8.4.3/bin/ghci -XTemplateHaskell GHCi, version 8.4.3: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration from /home/rgscott/.ghci λ> import GHC.TypeNats λ> ''(*) GHC.TypeNats.* }}} {{{ $ ~/Software/ghc/inplace/bin/ghc-stage2 --interactive -XTemplateHaskell GHCi, version 8.5.20180617: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration from /home/rgscott/.ghci λ> import GHC.TypeNats λ> ''(*) <interactive>:2:4: error: parse error on input ‘*’ }}} int-index, I believe this was caused by your commit d650729f9a0f3b6aa5e6ef2d5fba337f6f70fa60 (`Embrace -XTypeInType, add -XStarIsType`). Do you know what is going on here? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15284 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
