I run “make” before starting the REPL to avoid the problem you mention
(bah!), but from there on I can happily hack on my stuff.
A little-known feature of Emacs-Guix is C-c . u (guix-devel-use-module),
which allows you to load a module without compiling it with C-c C-k.
It’s fast and non-intrusive, unlike C-c C-k.
