I think I'm missing something. That link shows how to specify which version to include, but I don't see where it specifies how they are stored. Specificaly it says "Modules posted to CPAN or entered into any standard Perl 6 library are required to declare their full name so that installations can know where to keep them, such that multiple versions by different authors can coexist, all of them available to any installed version of Perl." Any ideas if that has been decided yet? /me considers overloading use to pull modules out of a database just for kicks. ;)
