Hi all,
I was looking at the grammar defined at
http://wiki.ecmascript.org/doku.php?id=harmony:modules (Last modified:
2012/02/27 17:27 by samth) and noticed conflicting states during
tokenization. Consider the following expression:
export x, y, z;
According to the grammar defined in the wiki, this expression might have
two (undecidable) tokenized forms:
ExportDeclaration
-> ExportSpecifierSet
-> Id
-> Id
-> Id
ExportDeclaration
-> ExportSpecifierSet
-> Id
-> ExportSpecifierSet
-> Id
-> ExportSpecifierSet
-> Id
The issue here is that parsers won't be able to choose one form or the
other.
I've posted a possible fix for the grammar here:

Hope this helps,
Regards,
