10:02 PM Ruby Feature #21827 (Open): Deprecating Ripper

I think it is time to consider deprecating `Ripper`.

07:43 PM Ruby Feature #6012: Proc#source_location also return the column

And he also made it clear it was just too late in the release cycle to address #21783 and #21784, see https://bugs.ruby-lang.org/issues/60... Eregon (Benoit Daloze)
