Re: [RFC] [Feature] In project `configuration.scm` allow dependencies to other repos with `configuration.scm`

[Josh Marshall <joshua.r.marshall.1991@gmail.com>]

This is a technical workaround, not direct support.  If such a feature
is to be aimed at general developers and researchers, it can't be so
circuitous. The Invocation from any form of Guix installation needs to
be `guix shell` and just work.
https://guix.gnu.org/manual/en/guix.html#package_002ddevelopment_002dmanifest
 Would need to be extended to take a URI and git reference for
individual dependencies.
