I am not aware of that puzzle, or what Jeff had in mind, but here is my guess: it lets you add code to an 'any clause without breaking the 'any, e.g. if you want to call a sequence of functions until one of them returns non-none/false, but also need to do some calculations in between, you could use something like: any [ func1 to-none count: count + 1 func2 to-none count: count + 1 func3 ... ] -- Holger Kruse [EMAIL PROTECTED] -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
