Anyone seen a Javascript interpreter in Python?

I've never seen it actually done but it's not that bad idea and I've
thought about it on various occasions, mostly for the purpose of
writing robot web clients in Python that could deal with JS on
downloaded pages.  Pythoneers don't like to admit it but Python's
semantics are not that distant from JS's.
