Not sure yet what to do with methods which are used at different
locations- e.g. the nullmethod is used all over the place.
+ EDIT: flashplayer doesn't allow this anyway- a method can only
+ be used once
Also, I have the strong suspicion that flash player uses only
the difference between max_scope_stack and init_scope_stack, anyway.
