Hi

just a curiosity: are there any official plans to switch to version 4 of
ANTLR, which automatically deals with left recursion?

thanks in advance
Lorenzo

No, we don't have such plans. Why are you asking?

Best regards,

Well the automatic handling of left recursion in ANTLR4 would make
writing grammars easier, but that is not crucial of course.
