I just added a configuration for programming in Hy. This is the first step for
moving more of my Emacs configuration into guix home. Instead of adding the
autoload for ‘oni-hy’ in the ‘oni-core’ package, I've added it directly to my
Guix configuration. In the future I'll want to change this so that each package
gets its own configuration and also extends my Emacs configuration so that it
automatically adds these autoloads when I add a package.
