Issue #20242 has been updated by Eregon (Benoit Daloze). Oh right, that makes a lot more sense. I wonder if it could be a configure flag or so to disable that warning, until it's stable enough to remove the warning entirely. ---------------------------------------- Misc #20242: `--parser=prism_without_warning` https://bugs.ruby-lang.org/issues/20242#change-106687 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal ---------------------------------------- I was hoping to add another option to `--parser` which would be `--parser=prism_without_warning`. The issue is that it's making it hard to run the tests/specs that test against the output of stderr. This would do the exact same thing as `--parser=prism` it just wouldn't warn. (The name is derived from `--dump=insns_without_opt`, but I'm okay with anything. -- https://bugs.ruby-lang.org/
