Mmmm, well, Shedskin takes Python source as input, does type inference 
and produces C++ source, then compiled as normal. But yes, it is a 
restricted Python, but AFAICT not at all as restricted as Slang.

So I wouldn't say Slang is really fair - being C in disguise :)

BUT... Unladen Swallow and IronPython might be interesting to test too. 
Unladen has a goal of being at least 5x faster than CPython, which in 
the light of Cog seems like a rather modest goal. AFAIK it is not fast 
at all right now though.

Still, as we all know - Python *is* and probably always will be 
*CPython* - all other implementations will be "imitations" with limited 
auidences. Now I note there is a py3k-jit branch, but someone mentioned 
that it hasn't moved in 7 months.

Pypy is probably the only project that possibly could step in and 
"become" a next generation platform for Python - or what do you guys 
that have more insight into the Python community than I do?
