Do you mean it only gets defined when standard (instance & class based)
searching methods fail?

Object Manager doesn't specifically, but Implicit does, you can see it
if you print out its '__class__.__dict__'.

Exactly what I need! :-)  Thankfully these methods that I need defined
at runtime only come from one other object, so it appears I can override
the __of__ method to work the magic for me in conjunction with
containment acquisition.
