Although any such patch should discuss how it compares with Cesare's work on wpython. Personally, I *like* CPython fitting into the "simple-and-portable" niche in the Python interpreter space. Armin Rigo made the judgment years ago that CPython was a poor platform for serious optimisation when he stopped working on Psyco and started PyPy instead, and I think the contrasting fates of PyPy and Unladen Swallow have borne out that opinion. Significantly increasing the complexity of CPython for speed-ups that are dwarfed by those available through PyPy seems like a poor trade-off to me. At a bare minimum, I don't think any significant changes should be made under the "it will be faster" justification until the bulk of the real-world benchmark suite used for speed.pypy.org is available for Python 3. (Wasn't there a GSoC project about that?)
