That's exactly what we're trying to do.  Greg has the advanced
consistency checking, and I've been trying to remove ambiguities and
warts in the current rule corpus, and simultaneously come up with some
extensions to the current language that will let us remove *more*
warts.  The extensions are designed to completely supplant certain
existing constructs which I consider ugly and difficult to parse.

To paraphrase Orwell: it was intended that when Newspeak had been
adopted once and for all and Oldspeak forgotten, a buggy parser should
be literally unimplementable, at least so far as implementation is
dependent on clear syntax and reasonable semantics.
