Hi, personally, I feel that you should be able to assign numeric value to each element (and have them implicit if not specified). This is imho better for serialization (but it can be done with names as well, yeah) - but more importantly, it also allows usage with bitwise operators, so you could use them as a "flags" (ie. $weekend = Days::SATURDAY | Days::SUNDAY).
