Hi folks,
I have a parser problem. I have a basic calculator program (Graham Hutton's from Nottingham) which contains the following code:
-- Define a parser to handle the input expr :: Parser Int expr = do t <- term do symbol "+" e <- expr return (t + e) +++ return t
I assume that the nested 'do' (before 'symbol') is too much. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
