#13401: GHCi gives conflicting information about visible type application -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: GHCi | Version: 8.0.1 Resolution: | Keywords: | TypeApplications Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #11376, #11975 | Differential Rev(s): Phab:3310 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ryan Scott ): In [changeset:"b335f506f1d3a766de849e015f6732ae130247a4/ghc" b335f50/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="b335f506f1d3a766de849e015f6732ae130247a4" Further document :type +v's role in analyzing -XTypeApplications in GHCi Summary: The section on `-XTypeApplications` in the users' guide isn't terribly clear on how to view the visibility of a function type signature's type variables in GHCi properly (i.e., using the `:type +v` GHCi command). This adds some more exposition that demonstrates how to use `:type +v` (and why you don't want to use `:type`). Fixes #13401.
