#11170: (read ".9") :: Double unable to parse -------------------------------------+------------------------------------- Reporter: varosi | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 7.10.2 Resolution: | Keywords: Read Operating System: Windows | Architecture: x86_64 Type of failure: Incorrect result | (amd64) at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ekmett): In the past we've avoided in the past making GHC-specific changes in what `read` will accept to avoid hard to track down differences across compilers. We've rejected at least one similar generalization request (binary literals) on those grounds. #10092 That said, there is already a chink in that armor as I believe we've let in a patch in that generalized `lex` to allow a bit more unicode. #10444 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11170#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
