I'm not a laywer, but if a future version of 'perl' were released under
a different license, I strongly doubt that this would retroactively
change the licenses of any earlier works. That's exactly what would
happen in Guix if we write (license (package-license perl)) and then
later change the 'license' field of the 'perl' package.
