You are absolutely right!

We are not here for language design.
That's already done by Guido, and he is
right about it. We just want to try a
different implementation. This is a high
risk to be just a waste and something that
the core group cannot afford to try, due
to lack of time.

What we effectively are doing is a prototype
of a new implementation based upon new
techniques. This is explorative programming,
pioneer work, an experiment.
We will see if it succeeds. It will help Python
either way.
