Thanks! This looks mostly good, see comments below. Can you send an
updated patch that also includes copyright information? Thanks in
advance!

There is a pledge at the top of perl.scm asking to add packages in
alphabetic order. Can you adjust the location of this expression
accordingly?

Synopsis should not start with an article. `guix lint` will complain
about this ;-)

Also, the line breaks after home-page and synopsis are not necessary.

Otherwise LGTM!
