Great! What about instead of (or along with) "-t cran -t elpa", use a comma separated list as it is done in "guix lint --checkers=..."? I think "--foo=one,two" is a general syntax, so it would be good to support it. Also this will allow to complete several updaters in a guix-refresh popup (M-x guix r =t). -- Alex
