[Haskell-cafe] Interaction in Haskell

Hi, im using Hugs 98 and learing how to use interactive Haskell. As read in the book: capitalise :: [Char] -> [Char] capitalise = takeWhile(/='.') . map toUpper interact capitalise its said the program is FULLY INTERACTIVE, i.e: as soon as 'h' typed on the keyboard, an 'H' appears on the screen. But the program above always waits untill ENTER was hit to display the result Is this normal ? Is the book right ? I thought if the list was evaluated lazily, then it should be fully interactive. Cheers. _________________________________________________________________ Be the first to hear what's new at MSN - sign up to our free newsletters! http://www.msn.co.uk/newsletters
