GHCi: No instance for (Show (IO ()))
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"?
