Observable and Observer go hand in hand. We're talking about both.
Specifically, I want to add observable to TPersistent.
People having object frameworks based on that class will really thank you
for slowing their systems.

I'm not adding any calls to it. Just a call and a property which - when used in
a
descendent - may instantiate an auxiliary object. By default, nothing is
called, and therefor there is no speed impact.
