I think Andy wanted to take a look at developing just the support to
references values by position rather than by alias without waiting on the
bigger task. I don't think that is possible; at the least it is A LOT of
work much of which might change later when we do work on the bigger task.
I know personally, time/resources aside, the biggest reason I have not
worked a lot on the bigger task (other than my initial work on the new
query parser) is because I had hoped a solution would present itself to the
Antlr 4 quandary. But it hasn't and likely wont and I think Gunnar and
Sanne and I are all in agreement that it probably just makes sense to base
this work on Antlr 3.
