That's true. But it's not like they are much more manageable in for
and while loops, either. But having to deal with enumerations, instead
of "just" using a method call, is cumbersome at best, error prone at
worst, especially when working on the code alone.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
