[antlr-interest] Need some advice which ANTLR versions should be used for my project (Target: Java or Python)

[Jim Idle]

I think that your choice is 3.4 and Java as the Python target does not
seem to be maintained. If you used an older version then it is likely you
would hit problems with python that are not going to be fixed and you
would be stuck.
