GNU Guix launches

BTW, I believe Guile comes with a reasonably functional implementation of ECMAScript these days.

Really? Since when? Manual says ECMAScript was not the first non-Schemey language implemented by Guile, but it was the first implemented for Guile's bytecode compiler. The goal was to support ECMAScript version 3.1, a relatively small language, but the implementor was completely irresponsible and got distracted by other things before finishing the standard library, and even some bits of the syntax. So, ECMAScript does deserve a mention in the manual, but it doesn't deserve an endorsement until its implementation is completed, perhaps by some more responsible hacker.

Not a ringing endorsement to say the least. The only language which is kinda-sorta-maybe-supported is Emacs Lisp and it's not clear why anyone will want that if they don't like Scheme.

P.S. It's funny, really. Guile is still pushed really hard by FSF backers and it's used in some fringe projects (like Lilypond, or Gnucash, or, I don't know, Guix) but when serious people need real scripting for their real needs they choose... something else. In fact you can easily see when project built around guile tries to finally reach normal people: it's when guile is finally get a sane alternative.
