Can you give real names to A, B, and C? What roles are they playing? Can B and C be specializations (subclasses) of A? Can B and C ask A what the current proxy setting is? If you had three people named A, B, and C, what would their job titles be, what would each of them know, and what would they have to get from each other?

A global variable is like person B riffling through the desk drawers belonging to person A just to get some info he knows. It's better to ask, not steal from behind. Because what happens if person A no longer puts it in the same drawer?
