I believe Cython is about this as well -- the extensions to the language
is only because we have to (because Cython isn't smart enough in places
where we need speed), not because we want to (except for communicating
with native C libraries, that is).
Compiling as much pure Python code as possible is definitely a goal for
Cython. Of course, within the context of egtensions loadable into the
CPython interpreter. We are happy to accept patches that make pure
Python code without any Cython-specific syntax run faster. We also have
a mode using Python decorators to provide types ("pure Python" mode of
Cython).
As Stefan noted, ShedSkin compiles Python to C without CPython. Of
course, doing something from scratch can be fun and a learning experience.
