You could use bit flags to avoid the array issue. Your point about constants is reasonable although given that it's a one-time cost and there are already automated tools to do this for many popular languages, I don't think it presents a real barrier. Edit: I see they originally use a bit mask and then changed to the space-separated string. http://www.tedunangst.com/flak/post/string-interfaces http://www.tedunangst.com/flak/post/string-interfaces
