What's the current state of support for beginless ranges? From https://github.com/jruby/jruby/issues/6464 it looks like the task is done, which seems consistent with the change history of RubyRange. But when I fire up jirb and try it out, I get a syntax error. Is there a flag I need to set?
Jason Lunn: It is on master which will be in 2.4 which is Ruby 3.1. So we are jumping from 2.6 to 3.1
It is already implemented and I don't think we have any outstanding broken tests for it
So I'd need to build from source in order to kick the tires at the moment?
