#3452: Show type of most recent expression in GHCi -------------------------------------+------------------------------------ Reporter: ozy | Owner: Type: feature request | Status: patch Priority: lowest | Milestone: 7.6.2 Component: GHCi | Version: 6.10.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by leroux): Instead of completely removing the following error. {{{ λ: id <interactive>:2:1: No instance for (Show (a0 -> a0)) arising from a use of `print' Possible fix: add an instance declaration for (Show (a0 -> a0)) In a stmt of an interactive GHCi command: print it }}} I think it would be saner and possibly better to just append the {{{:t}}} of {{{it}}} to the preceding error message. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3452#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
