As far as I know, these are all still active, although possibly experimental: Pynie (Python for the Parrot VM) WPython (16-bit word-codes instead of byte-codes) HotPy (high-performance optimizing VM for Python) Skulpt (Javascript implementation) HoPe (Python in Haskell) Berp (another Python in Haskell) WPython in particular seems to be very promising, and quite fast. I don't understand why it doesn't get more attention (although I admit I can't criticise, since I haven't installed or used it myself). http://www.pycon.it/media/stuff/slides/beyond-bytecode-a-wordcode-based-pyth... In the Java world, there are byte-code optimizers such as Soot, BLOAT and ProGuard which apparently can speed up Java significantly. As far as I can tell, in the Python world byte-code optimization is a severely neglected area. For good reason? No idea. -- Steven
