Category: GHCi Group: 6.4 Status: Open Resolution: None Priority: 4 Submitted By: Simon Marlow (simonmar) Assigned to: Nobody/Anonymous (nobody) Summary: GHCi: No instance for (Show (IO ())) Initial Comment: >From Wolfgang Thaller: This behaviour (from today's stable branch) is slightly confusing: > Prelude> print id > > Top level: > No instance for (Show (IO ())) > arising from use of `print' at Top level > Probable fix: add an instance declaration for (Show (IO ())) > In a 'do' expression: print it > > <interactive>:1:0: > No instance for (Show (a -> a)) > arising from use of `print' at <interactive>:1:0-4 > Probable fix: add an instance declaration for (Show (a -> a)) > In the definition of `it': it = print id The second message makes sense, but the first one doesn't. Also, what's the difference between "Top level" and "<interactive>:1:0"? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=1156554&group_id=8032 _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
