#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): What should `:t bar @Int` say? I answer: the same as whatever type we infer for {{{ it = bar @Int }}} I guess that's answer (3): `it :: forall {b}. Int -> b -> Int`. No, it doesn't imply that `bar @Int @Bool` is illegal, any more than inferring that type for `it` implies that `bar @Int @Bool` is illegal. Use `:info` if you want to see which variables are specified! This rule is simple. Just infer the type, precisely as if it was a let- binding. No more and no less.
