-----------------------------------------------------------------
Uwe, would it be possible to move the implemented visitor methods from the
JavascriptCompiler into a private static inner class inside of the
JavascriptCompiler to hide them properly and then make all the other public
classes package protected through regexs like we already do for some of the
classes in the build.xml file? Would this satisfy the requirements of keeping
all the ANTLR methods hidden or is there more that I'm missing?

>
> I would like to upgrade ANTLR from 3.5 to 4.5. This version adds several
> features that will improve the existing grammars. The main improvement would
> be the allowance of left-hand recursion in grammar rules which will reduce
> the number of rules significantly for expressions.
> This change will require some code refactoring to the existing expressions
> work.
