        // capitalize on that with some enums by making the const VALUES
        // array a key value pair of the value itself so that we've
        // essentially got value => value for each item in the const VALUES
        // array. This way we can take advantage of the quickness of isset over
        // in_array. However, because not all enums may do this we need to
        // ensure if the value isset as the key in the array that it also
        // matches as the value of that item in the array, otherwise we'll
        // get false positives where its a normal array of 0 => value, 1 =>
        // value and we check for 0 being a valid value where it may very
        // well not be valid at all.
