That’s also something I’m interested in.  For example, I’ve done things

  M-x compile RET guix environment … -- make -j4

in the past, but it’s inconvenient and respawning ‘guix environment’
every time is inefficient.

It would be nice if we could somehow attach an environment to a buffer,
and for instance have M-x compile operate under that environment.

Another interesting thing would be the ability to have Babel snippet
specify their complete environment, instead of just the language.  For
that we’d need help from Emacs-Guix to keep track of existing

Maybe if Alex Kost is reading this they can comment.  :-)
