[CentralOH] Singleton

[Eric Floehr]

To answer your original question (sorry got sidetracked by the singleton in
general)...

I think your deleting the class should work, except if you ever want to be
able to subclass or use isinstance().  There may be a few other edge cases
where not having the class available might be inconvenient.
