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.
Sanne? Gunnar? ;)
