So you want to write a fast Python?
I have some questions:<p>* Is the Jit in PyPy standalone, i.e. can it be used by other projects independently of Python? Is it documented?<p>* How does PyPy compare with highly optimised C?<p>* Assuming that the benchmarks that used to be at the Computer Benchmarks Game for PyPy are somewhat representative of overall performance, why is there still such an enormous difference with optimised C?<p>* There used to be this thing called restricted python. If one limits oneself to using that only, are benchmarks much better?<p>* I read somewhere that some projects have merged or combined forces. There used to be this thing called Unladen Swallow. There was also Psyco. Have either of these merged with/been absorbed by PyPy? Are any other such projects still going?<p>* Cython is another fast project. If it became part of mainline Python, would PyPy become irrelevant?
