I am very interested in the grammar, but have three questions in advance 
of seeing the grammar.
1) Does it fully handle virtual semicolons? I see that the base code 
(scriptonite) has a special lexer to handle some of the more quirky 
issues of javascript dealing with new lines.
2) Does it produce a tree?
3)  How does it recover from badly structured input?

alternatively, just provide the grammar and supporting files. The 
answers should jump out.
