What would you think about WITH-CHANNELS that would accept a list of
channels and evaluate any package reference in its body within an
inferior of those channels?
E.g.
(with-channels %my-channels
(package
(name "yay")
…
(inputs
(list foo bar baz)) ;these are all looked up in %my-channels
…
(license gpl3+)))
