#12363: Type application for infix -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: feature request | Status: new Priority: lowest | Milestone: Component: Compiler | Version: 8.0.1 (Parser) | Keywords: Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by AntC): I'm perturbed by the type argument appearing after the infix operator; whereas with a prefixed function the type argument comes first. In {{{ instance Eq a => Eq [a] where ... (x:xs) == (y:ys) = x == @a y && xs == @[a] ys }}} the prefix form would put `@a` before `x` So my brain has to parse that as `x (== @a) y`. Shouldn't it be like this {{{ (x:xs) == (y:ys) = @a x == y && @[a] xs == ys }}} I notice in @dredozubov's #14446, the `@"foo"` comes before the operator. As to whether the syntax becomes less scary from looking through the examples: no, to me it still looks like perl or Teco. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12363#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
