#8068: ghc incorrectly accepts the Kannada TTHA character at the beginning of an identifier. ------------------------------------+------------------------------------- Reporter: malcolmw | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- The code at http://hub.darcs.net/lelf/acme- lookofdisapproval/browse/Acme/LookOfDisapproval.lhs is accepted by ghc, but technically, the leading letter of the funny identifier (Kannada TTHA) is neither lowercase, uppercase, nor titlecase. It can be accepted in any position of an identifier except the first, where Haskell requires the character to be either upper/title-case (conid) or lower (varid). isLetter x && not (isUpper x) does not imply isLower(x). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8068 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
