This update addresses two problems — first, the keyword “import” is no longer considered a token so people using the excellent new “Components.utils.import” stuff in trunk mozilla can, well, use it without having it reported as a syntax error.

Second, I hacked support for the “let” statement into the parser to the point where you can use it wherever you can use “var”. This is obviously no where near the full usage of “let”, however I think it is a pretty common case and should be enough for people who want to used it as a narrowly scoped “var”.

Also note that I have not updated the scope checker to support let — it may not be possible without a major rewrite as I don’t believe I wrote that with only function level scope in mind.
