You bet! Power to the Guix :)

Thank you, and sorry for the linting issues. I get busy and then rushed
and I make these stupid mistakes.

I focused on the SBCL packages and then retroactively went back and
added all the ECL packages, trying to be a good citizen. In retrospect,
this was not a good idea. Common Lisp code is not guaranteed to work
across runtimes.

If you're OK with it, I would just go ahead and delete any ECL package
that doesn't immediately work. I can do this myself, but I'm currently
on holiday and won't be able to take a look for another week and a half.

I think ECL is used outside embedded contexts, but I haven't found a
reason to use it yet. If I remember correctly, I think one compiles
faster than the other, and the other runs faster, so some people switch
between the two when developing and then deploying.
