Viper: yet another python implementation

[Bruce Dodson]

Ni!  I don't see the point of creating a variant of python that aims to be
more efficient, but does so at the cost of taking away Python's most
powerful optimization mechanism: external C modules.  I also think that a
python that has enough knowledge of types to perform inlining... well, such
a beast is no longer Python, no matter how similar the syntax appears.
