All I know is that the ES1-3 grammar was hard to squeeze into Bison/Yacc 
(think of automatic semicolon insertion!) for the KDE JavaScript 
interpreter. Next version will work without for greater flexibility and 
better error reporting.

That being said, there are of course much more advanced parser generators 
these days that have more sophisticated input languages.
