#11409: Cannot instantiate literals using TypeApplications -------------------------------------+------------------------------------- Reporter: Feuerbach | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1-rc1 Resolution: | Keywords: | TypeApplications Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonpj): * owner: => goldfire * keywords: => TypeApplications Comment: It'd also be possible to define {{{ integerLit :: Integer -> forall a. Num a => a integerLit n = fromInteger n }}} arrange that `3` elaborates to `integerLit 3` :: forall a. Num a => a`, and now that will work as expected. This is so simple to do that it might be worth doing, just to avoid documenting the infelicity. After all, Haskell advertises that `3 :: forall a. Num a => a`, so it's annoying if it doesn't behave like that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11409#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
