Sure, I was just pointing out that you can avoid even these things if
you choose the Artistic license.  I have no problem with the GPL, but
some people do.  The other possibility (if the current Perl "GPL or
Artistic" is not a possibility) is simply upgrading to the "Artistic
2.0" license adopted by the Perl Foundation for Perl 6 and later (I
think?):

http://www.perlfoundation.org/artistic_license_2_0

it's a GPL-compatible free software license.
