[GHC] #12969: Rebindable enumFrom etc. syntax
#12969: Rebindable enumFrom etc. syntax -------------------------------------+------------------------------------- Reporter: cactus | Owner: Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 (Type checker) | Keywords: | Operating System: Unknown/Multiple RebindableSyntax | Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Constructs like `[x..]` or `[x..y]` etc. seem to use wired-in `enumFrom`, `enumFromTo`, etc. names even when `RebindableSyntax` is turned on. I think we should allow these to be shadowed by the user the same way they can shadow other syntax desugarings. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12969 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

You need `-XOverloadedLists` on to get this; see the [https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts... #overloaded-lists manual section]. I'll add a note to the user manual. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12969#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
