So, it functions with ECMAScript semantics everywhere? This is an
important consideration. A Python integer is not the same as an
ECMAScript number (which is a float), and a Python string is not the
same as an ECMAScript string, and a Python dictionary has attributes
and keys which don't collide.

I'm more than a little tickled by the PyPyJS project:

http://pypyjs.org/

That's PyPy running in your web browser. The semantics are 100%
Python, but... uhh, it does require a fairly hefty download of code
before it can do anything. That _is_ a bit of a downside, but it's
still a pretty cool project!
