Jon: You may not forget that you are testing for micro benchmarks.
Surely, a Python will never become faster in the long run. However, all
the things will change if we were benchmarking really complicated code
of many thousand of lines.

When I was younger (now I am 31) I also believed benchmarking is a
must. However, in the meantime it is even this: if your ray-tracer in
OCaml were 100000 times faster than the Bigloo-Scheme version I would
not opt for OCaml quickly. Perfromance is important, no question, but
in a code project it is a rather tiny part.
