#11376: Inconsistent specified type variables among functions and datatypes/classes when using -XTypeApplications -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.1 checker) | Keywords: Resolution: | TypeApplications Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Hang on. Isn't there already somewhere in VTA where you already instantiate where it's not strictly necessary? Maybe somewhere like {{{ f x = g }}} where `g` has a polytype. With lazy instantiation you might well get an inferred type {{{ f :: forall a. Eq a => a -> forall b. Ord b => blah }}} but I think we don't. I think there is somewhere this happens, although I am not sure where. The `:t` context looks to me like another place where this eager instantiation should happen, no? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11376#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
