#14288: ScopedTypeVariables with nested foralls broken since 8.0.2 -------------------------------------+------------------------------------- Reporter: MikolajKonarski | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.2.1 checker) | Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: GHC rejects | (amd64) valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): I don't see what is strange about this? It's no stranger than `f :: forall a b. a -> Int -> (a, b)` at least, which is accepted. Replying to [comment:8 goldfire]:
Note that the quantifier for `b` hasn't been encountered in the term definition, which takes only one argument.
Yeah... and? I don't see what the term definition has to do with anything here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14288#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
