I run =E2=80=9Cmake=E2=80=9D 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=E2=80=99s fast and non-intrusive, unlike C-c C-k.
