Sounds like something I have been thinking of (except yours is taken to
the next level). I was thinking of using something like ANTLR as the
parser and then doing an AST transform to generate a valid Python AST -
allowing me to experiment with adding new language features as syntactic
sugar.

Your idea is better of course. :-)
