So there is a reason? ;)
In this example, I wouldn't want Array to implement "increment" as a
method -- only Numbers should have increment available (just as Array
doesn't have "addClass" but Elements does). The example may be
trivial, but if it was a list of more complex instances it becomes
more evident.
