Re: [hibernate-dev] Query handling : Antlr 3 versus Antlr 4
This seems very similar to what I had in mind with the decorator stuff. The
decorating elements would represent that manually implemented semantic tree.
In the end it probably doesn't even matter whether the elements of that
tree would have links to the parse tree elements they originated from or
whether that tree is completely "stand-alone". As you say, we'd
traverse/alter it with our own listeners. In my understanding that's as
good as it gets with Antlr4.

I am not so sure that manually building a tree that would work with
listeners/visitors generated from a second grammar is going to be an
option. I have asked on SO and on the Antlr discussion group and basically
got no responses as to how that might be possible. See
https://groups.google.com/forum/#!topic/antlr-discussion/vBkwCovqHcI
So the question is whether generating a semantic tree that is not Antlr
specific is a viable alternative. I think it is. And we can still provide
hand written listener and or visitor for processing this.
