#13401: GHCi gives conflicting information about visible type application -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new 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): Wiki Page: | -------------------------------------+------------------------------------- Comment (by crockeea): I **really** appreciate your explanation. I frequently use GHCi to learn about my program, and it's extremely unhelpful when it lies to me (see [http://chat.stackoverflow.com/transcript/message/35984292#35984292 this] for another example.) Therefore it seems like type application visibility information should ''only'' be displayed with lazy constraint instantiation, i.e., when the `+v` option is used. Then there's no convoluted explanation needed, and more importantly, you will always get correct information. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13401#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
