Hi Guillaume,

thanks for the big patchset, looking very good overall!

A few general nits:

- You didn't define any "ecl-" package.  Could you define them for all the
  packages (unless they are known to be broken with ECL)?
  I know some packages lack the ecl- definition, this should be fixed :p

- 6 commit messages lack a period on the first line.
  If you use Emacs, you might find this yasnippet useful:
  guix/etc/snippets/text-mode/guix-commit-message-add-package

fprog:
  - Description should start with a capital, or here maybe with @code{fprog}.

cambl:
  - is spelled in all-caps ("CAMBL") according to the README.

cl-containers:
  - synopsis: "Container library ..."

  - I'm realizing the sbcl-lift does not have the right version number, which
    should be (git-version "1.7.1" ...).  Can you update this?

bst:
  - 1.1 is out ;)

cl-octet-streams:
  - Description should start with a capital, or here maybe with @code{cl-octet-streams}.

cl-lzlib
  - License seems to be GPL-3, not GPL-3+, but since this is your library, the
    decision is all yours ;)

Thanks a lot for this great contribution to "Common Lisp on Guix" :)
