Most of the Guix distribution depends on Perl, and most of the rest
depends on Python ;)

Try `guix refresh -l perl`.

So, changing the build systems for these languages will require you to
rebuild almost everything.

Changes like this will need to go on the core-updates branch, where we
make changes to the core of the system.

You could create a separate perl-test-build-system and use it for your
test packages.
