hi, good ... morning : ) I am just confused by the following code
oneOnly :: [Int] oneOnly = [1] isOneOnly :: [Int] -> Bool isOneOnly oneOnly = True isOneOnly tester = False
what I want to do is to define a 'type' oneOnly as [1] and use it on the pattern matching in function isOneOnly. But it does not work as I expect: When I type isOneOnly [1] it will be True which is the result I expect but for is OneOnly [1,2] the result keeps True, it seems the second pattern has been ignored, I think I try to achieve the purpose in a wrong way, any suggestion? Thanks and Merry Christmas Best wishes, Raeck _________________________________________________________________ Send e-mail anywhere.
