#12164: Type signatures in patterns not (yet) handled by Template Haskell -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Template Haskell | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2490 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Yes, I imagine without scoped type variables, this wouldn't be so hard. With them might be more challenging. Does your use-case require binding variables in the pattern type signature? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12164#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
