[1 of 1] Compiling Main ( prog.hs, prog.o )
prog.hs:3:16:
No instance for (Typeable c0) arising from a use of `typeOf'
The type variable `c0' is ambiguous
Possible fix: add a type signature that fixes these type variable(s)
Note: there are several potential instances:
instance [overlap ok] Typeable ()
-- Defined in `Data.Typeable.Internal'
instance [overlap ok] Typeable Bool
-- Defined in `Data.Typeable.Internal'
instance [overlap ok] Typeable Char
-- Defined in `Data.Typeable.Internal'
...plus 18 others
In the second argument of `($)', namely `typeOf zipWith'
In the expression: print $ typeOf zipWith
In an equation for `main': main = print $ typeOf zipWith
