The apple javascript parser (and maybe V8) don't use a LL(1) parser and
still cope with ASI so maybe there are alternatives to this... but yep, for
better error messages someone should take better care of the parser.

would be nice to have python regexes as a start in the js interpreter...
but I don't know if the pypy-python interpreter code is reusable.

They are only supported in firefox and flash so I don't think too many
people use it, but then if needed you can try
https://github.com/laverdet/js-xml-literal

What I would work on is:
 - having more granular tests
 - jit support
 - benchmark suite
 - co-routine support, for having something like gevent for javascript
 - ???
 - profit

If you could have a fast javascript vm with gevent instead of pure callback
based programming could be a good alternative to node.js
