And Python's list.sort is just a wrapper around C code. So I guess
that it's not fair to use that, or any other Python built-in function,
in a Python-vs-X speed shootout. This would mean you can't use Python
classes in such a shootout either, as type.__new__ and object.__new__
are both also merely wrappers around C code ... not to mention Python
dictionaries: wrappers around C code which are used in just about
every name lookup in Python.

So, the conclusion is that it's not fair to use Python in a
Python-vs-X speed shootout. 

I rather like that conclusion :-)
