#13039: Add options to select GHCi prompt type errors -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: feature request | Status: new Priority: low | Milestone: 8.4.1 Component: GHCi | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): I don't like the idea of adding options here since they will only benefit those who know about them; and I don't think those will be the same people as the people who have trouble with the existing behavior. (And if you really want to know why `void e :: IO ()` didn't type check then you can enter `void e :: IO ()` into ghci; and that's much more obvious than turning on an option.) I do think that it'd be reasonable to improve the (default) behavior when `e` type checks but `print e` does not (presumably due to a missing `Show` instance). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13039#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
