#8708: Kind annotation in tuple not parsed -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 (Parser) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by thomie): What about the following: * unboxed tuples: `(# Int, Int :: * #)` * lists: `[ Int :: * ]` * parallel arrays: `[: Int :: * :]` * default declarations: `default ( Int :: * )` Currently all of those don't allow types with kind annotation but without parenthesis. They only allow `ctype`s: {{{ -- A ctype is a for-all type ctype :: { RdrNameHsType } : 'forall' tv_bndrs '.' ctype { mkHsForAllTy (Just $2) [] $4 } | context '=>' type { mkHsForAllTy Nothing $1 $3 } -- A type of form (context => type) is an *implicit* HsForAllTy | type { $1 } }}} Implementation wise it would be nice to keep doing the same for all: either allow kind annotation without parenthesis, or keep the status quo (since 2002). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8708#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
