Not around here it ain't!  :-)  Okay, it's a function, but it 
is really a subroutine that doesn't return a value, right? 
Except for the fact that subroutines *always* return something
in Python, even if it's just None?

But in any case, I think attributes on objects are a special
case, as the object (the class, I suppose) is more in control
of when they are rebound, in general.
