I was expecting Clojure vs Common Lisp. I love scheme but it's not fair to include considering how few libraries there are (I don't even know if there is a package manager).
I remember reading about Raven when it came out for Cisco Scheme. I totally forgot about chicken scheme. I just remember being interested in Guile and sad that only guildhall was available.
The article mentions GNU Guix as "the" package manager for Guile Scheme.
Now, Guix includes some 15000 non-Scheme packages, so it is somewhat "overkill". OTOH you can also install/run/dockerize a world of Common Lisp packages with Guix. :-)
