Is there a JavaScript (ECMAScript) implementation written in Python?

Question

Are there any JavaScript (ECMAScript) implementations written in pure Python? It is okay even if its implementation is very slow.

Doesn't seem to be under active development anymore but you could check out pynarcissus, http://code.google.com/p/pynarcissus/source/browse/trunk/jsparser.py

Seems like a binding to V8 (JavaScript interpreter in Google Chromium) is available also, http://www.advogato.org/article/985.html
