The Perl 5 licensing is to make it as simple as possible for people to decide to use the project or contribute to it. The Artistic License 2 is what the main Perl 6 implementation components have chosen; the idea to offer it under that license as well is that porting to / using with Perl 6 becomes as easy as possible. The MIT licenses is offered so that the code can be used in different environments as well (like perhaps a contributor would like to port it, or pieces, to a different programming language.)
You could license your contributions in any one of those licenses, but we would appreciate if you could provide them under the same full set of licenses. If you've got objections or questions about the licensing, please don't hesitate to ask.
