for a comparison, the current (long) version:

guix build emacs-ement 
--with-commit=emacs-ement=8b56efa9387262514daf63151d41c9e111e79567

Obviously the difference is that --with-commit can apply to
dependencies, and this looks to only work on the actual package, but I
often find myself only adjusting the actual package I'm trying to build
anyway.

I'm not sure how @latest would work with @wip/find-room, unless @latest
was reserved to point to (maybe) the newest release. I think we've all
seen that the updater sometimes gets confused by some of the upstream
methods of tagging releases and trying to figure out what the lastest
release actually is.
