A: Prelude> let showParen = (undefined::[[[[()]]]]->()) Prelude> showParen $ 2+3*4 <interactive>:1:12: No instance for (Num [[[[()]]]]) arising from use of `+' at <interactive>:1:12 Probable fix: add an instance declaration for (Num [[[[()]]]]) In the second argument of `($)', namely `2 + (3 * 4)' In the definition of `it': it = showParen $ (2 + (3 * 4)) Prelude> -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
