#8750: Invalid identifier generated with Template Haskell not rejected --------------------------+------------------------------------------------ Reporter: | Owner: jstolarek | Status: new Type: bug | Milestone: Priority: normal | Version: 7.7 Component: | Operating System: Unknown/Multiple Template Haskell | Type of failure: GHC accepts invalid program Keywords: | Test Case: Architecture: | Blocking: Unknown/Multiple | Difficulty: | Unknown | Blocked By: | Related Tickets: | --------------------------+------------------------------------------------ I wrote Template Haskell code that generates this declaration: {{{ data (:+Sym1) (a:: Nat) (b :: TyFun Nat Nat) }}} `(:+Sym1)` is not a valid identifier and this declaration fails when I simply put it in a source file and try to compile it. However I get no errors when this definition is generated from Template Haskell. Not sure if this is intended behaviour or not. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8750 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
