Yes, which proves that it's viable. I notice that neither of them has
swept CPython away by massively outperforming them, so perhaps
reference counting isn't such a terrible idea after all?

I'm not disputing that refcounting has its downsides, but "likely a
bad idea to begin with" seems to be a bit beyond reasonable.
