Nice overview  :)

Now add here the syntax, and you know the winner.

> - The regular Squeak VM has not been overrun by CPython in these 6 years

> - Shedskin is the "state of the art" of statically compiling Python via C++
> using type inferencing etc etc - so I hear. It is said to be faster than
> Cython and Psyco. It ends up beating Cog, but "only" by a factor of 3x. I
> say "only" because that seems pretty good to me given that Cog is a JIT and
> still pretty young and that Shedskin can only run a subset of Python.
