#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: #11352 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I want to note that the Haskell Report says that `3` desugars to `fromInteger THREE`. Perhaps we can indeed hack around this by using `integerLit`. But then turning on `RebindableSyntax` would necessitate using `fromInteger`, which (due to its membership in the `Num` class), must have type `forall a. Num a => Integer -> a`, where the `forall a` just comes too early. This would mean that `3 @Int` would work with `-XNoRebindableSyntax` but then fail with `-XRebindableSyntax` (when importing `Prelude`). It would all be rather unexpected. Worse than the status quo? I don't know. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11409#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
