If the value of the flag can change during a run, I would do that. 
Otherwise, you have to make sure the local copy keeps in sync. Users 
might also think that it is a true constant that they could read once.

I understand that you might be concerned that one person in a 
multi-programmer project might decide to rebind xyz.flag and mess up 
everyone else. I think the real solution might be an option to freeze an 
entire module.
