[bug#40130] [PATCH 0/8] Add 'with-build-handler' and use it to improve UI feedback

[Ludovic Courtès]

Hello Guix!

This patch series is to always display upfront what’s going to
happen, even in the presence of “dynamic dependencies” (grafts),
as was reported at:

  https://issues.guix.gnu.org/issue/28310

With this patch, any time ‘build-things’ is called, we have an
opportunity to display what’s going to happen and to choose
whether or not to actually build things (dry runs).

I’m wondering whether/how this mechanism could be extended to
address:

  https://issues.guix.gnu.org/issue/22990

We’ll see!

Ludo’.
