Agreed, it was the assertion that "no Python code on earth...stands
a chance..." that I was objecting to.

There are many areas where the C code would have to be pathologically
bad to be beaten by Python, but there are plenty of places where only
slightly inefficient C code can be competitive relatie to Python.
