#11345: Template Haskell's handling of infix GADT constructors is broken -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: RyanGlScott Type: bug | Status: new Priority: normal | Milestone: Component: Template Haskell | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jstolarek): I think it would be better to add a field to `GadtC` that tells whether a constructor is an infix one or not. Correct me if I'm wrong, but information about infixity of a declaration is rarely needed. Adding a new constructor will force TH clients to implement handling of infix constructors even in situations where they don't care about infixity, whereas adding a new field to `GadtC` will be simple to handle - programmers can simply ignore that field in situations where it is irrelevant. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11345#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
