>You assert that Python hasn't progressed much, but you thumb down the project to progress it (Python 3).

I was talking performance wise. There are benchmarks from the Python devs out there that confirm what I wrote.

I did not speak about Python as a language in general. That said, if you want my opinion, Python 3 is not much progress in that regard either.

>Your assertion that optimization must always happen all at once is completely bogus

That's good, because I never asserted that. I didn't say that "optimization must always happen all at once", just that incremental optimization doesn't yield much benefits compared to a thorough interpreter rewrite with optimization in mind.

Python's history confirms this totally. And not only is Javascript a counter-example (all at once optimization getting huge results), but PyPy also is.
