#9194: Remove magic parsing of (~) -------------------------------------+------------------------------------ Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by goldfire): Replying to [comment:2 simonpj]:
Yes, I suspect that `(~)` pre-dated `-XTypeOperators`.
And, crucially, allowing type operators to skip the opening colon. Your comment does make me think that this change would then require users to specify `TypeOperators` whenever they use `(~)`. This would be a breaking change that would likely affect a lot of code, and perhaps for little gain. We could just special-case `(~)` not to require `TypeOperators`, but is that any better than the status quo? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9194#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
