I’m not sure about the legalities of dual-licensing. If you look at
licences like the GPL, they have wording that says “if you don’t
accept this licence, then you don’t have permission to use the
software”. That kind of precludes getting that permission via an
alternative licence ...

Can you show me the line of perl being under two licences? I'd like to
understand the point.

I have posted it before:

"Perl5 is Copyright (C) 1993-2005, by Larry Wall and others.

It is free software; you can redistribute it and/or modify it under the
terms of either:

a) the GNU General Public License as published by the Free Software
Foundation; either version 1, or (at your option) any later version, or

b) the "Artistic License".



For those of you that choose to use the GNU General Public License, my
interpretation of the GNU General Public License is that no Perl script
falls under the terms of the GPL unless you explicitly put said script
under the terms of the GPL yourself.

Furthermore, any object code linked with perl does not automatically fall
under the terms of the GPL, provided such object code only adds
definitions of subroutines and variables, and does not otherwise impair
the resulting interpreter from executing any standard Perl script. I
consider linking in C subroutines in this manner to be the moral
equivalent of defining subroutines in the Perl language itself. You may
sell such an object file as proprietary provided that you provide or offer
to provide the Perl source, as specified by the GNU General Public
License. (This is merely an alternate way of specifying input to the
program.) You may also sell a binary produced by the dumping of a running
Perl script that belongs to you, provided that you provide or offer to
provide the Perl source as specified by the GPL. (The fact that a Perl
interpreter and your code are in the same binary file is, in this case, a
form of mere aggregation.)

This is my interpretation of the GPL. If you still have concerns or
difficulties understanding my intent, feel free to contact me. Of course,
the Artistic License spells all this out for your protection, so you may
prefer to use that."
