Not all for loops are created equal.Considerfor x in [value1, value2, value3]You would expect to see x vary in the order of the values in the list. However – if x and the values are of an enumerated type, looping the “list” does NOT loop in the apparent order of the constant, but in the order of the enumerated type declaration, such as it would for any set.
