Woohoo!!

That’s <https://issues.guix.gnu.org/53127> but it probably needs work if
we want it to work reliably on all the packages.  My understanding is
that we’d need a “flag day” where we’d switch all Rust packages to
Antioxydant in one commit, is that correct?  Any ideas how to achieve
the big migration?

Efraim, thoughts on this?

Thanks,
