Good to know.  So a scope is a lexical scope of the method?  For the  
random code I type outside of a method, what "method" is it a part of?

Where is there an informal description of scoping rules and general  
syntax?  I'm beginning to think I should build a natural grammar from  
scratch rather than modify the yacc beast...that said, I do have it  
converted...it's just ugly.  Jean Bovet's nice ANTLRWorks tool did  
the left-recursion removal with a single menu item. :)
