Yes, but that's fine. A PL language that includes every programming paradigm would be a total mess, if even possible. Python has functional programming where it does not conflict with its overall design. The only place I find that this is not the case is with lambda, but that is now adequately fixed with the addition of the ternary operator. -- MarkJ Tacoma, Washington
