I haven't got a clue what STORE_GLOBAL is, apart from the fact that it 
looks like it has something to do with Python's bytecode.

If it's what I think it is (so don't hold me to this), it'd raise an 
exception if you used on something that hadn't been created yet. 
Probably need a MAKE_GLOBAL in addition to it, or keep STORE_GLOBAL as 
it is (for "var x = 0") and add MODIFY_GLOBAL that raises an exception 
on uncreated variables.

Or something. Again, I'm guessing, and you have me at a disadvantage. 
Can we keep the discussion above the bytecode level for now?
