Exactly the same way. The first argument to WITH-CHANNELS would be
(cons C G) and thus P and D would be picked from the set of C and G. C
and G can be specified with exact commits or branches, just like the
--channels option to “guix time-machine”.
We already have all the tools for WITH-CHANNELS — that’s (guix
inferior). We just don’t have a convenient syntax to do this without a
lot of boilerplate.
