#12363: Type application for infix -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: 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 Iceland_jack): The [[https://gist.github.com/llelf/6c01ded225877914f38a code] from #12507, whether or not it's supposed to compile, it would be nice to be able to specify the result type `r` {{{#!hs (?) :: forall r fields. Rec fields -> (fields => r) -> r Rec ? e = e }}} {{{#!hs access = record ? ?a }}} Doesn't compile, but {{{#!hs -- access :: (?a::Int) => Int access = (?) @Int record ?a }}} which could be `record ? @Int ?a`.. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12363#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
