Rather a lot of small changes to the front end to bring it up to parity with the May 5 grammar. Many of the new syntactic structures supported do not have back-end support, but in most cases intelligible errors are thrown. New in this patch: - removed support for - triple-quoted strings - xor operator (^^) - added support for - forward declarations of types, classes, interfaces - 'like' - 'this generator' and 'this function' - let block statement - slice expressions - spread expressions, spread patterns, spread types - array comprehensions - type application - yield without an expression - ... without an identifier - full object/array initializer syntax (a lot of hair here) - function types - super() statement in constructors - strings as literal namespace values Many bugs were fixed in the process. Performance is generally better, though early namespace resolution has introduced some performance regressions too. Note that there is no definer support here; the code performs namespace resolution but the namespace must be defined before the reference, and no values are tracked across files yet.
