We do not all use the same parser. At the very least, they're all
written in our local language. We use parsers that were originally
ports of the original parser, and while changing over the years still
match MRI's parser behavior.

If MRI and YARV do it, then we do it because that's what MRI and YARV do.

Minor nitpick :)
