I thought about this some more and realized this is not a workable
solution. The trouble is how will the class's object be found?
However, the situation is not as bad as that. If a class uses another
class, it should have a reference to it somewhere. This would avoid
the problem of the static methods completely (since the calling class
would have to exist and would have a reference). Of course, there are
still finalization issues.
