Pity that isn't as flexible as an object-instance -- can't define
special methods to determine how it will print, how it will
let usercode loop on its items, etc.

Lightweight-class instances, delegating all state to their
module, can implement whatever special methods may be
handy, and still avoid any need for the Singleton design
pattern as per GoF (my least-favourite GoF DP).
