--local vs. global variables will stop old programs too.

Not at all, at least not if it's done a certain way. V3 will have a mechanism for declaring variables local. Whenever a variable is not declared local, it is considered global. V2 has no way of declaring variables local. All V2 variables will be considered global. All V2 variables, currently, are global. Everything works.
