cpython

Also, the way you have described the CPython core developers and their efforts to improve the language is a bit disingenuous.

That could cause confusion with CPython (the main python implementation) and possibly also Cython (C extensions for Python).

The CPython implementation is, and it's still always been fast enough for everything I've written, so the meme is slightly overblown as far as I'm concerned.

The whole embedding vs extending debate is because of those globals and that CPython has been historically difficult to embed properly.

I meant only that Cython results would tell me more about relative CClasp performance than a comparison CPython does.

Plus, I believe Unladen Swallow is essentially a branch of the CPython source code while Jython was written from scratch.

Plus, if unladen swallow keeps its promise of doubling CPython's speed, then the gap between the two languages will once again be fairly narrow.

CPython can't eliminate one of the sides, since the calls (either to len() or to the slicing method of 's') might have side effects.

I hope to find security problems w/CPython which would likely help the world at large.

But historically, good ideas don't necessarily get adopted in CPython.

The use of the globals in the CPython interpreter are a fairly large design mistake that has prevented Python from having as much reach as other systems.

CPython is a good reference counted language.
