I would personally have no problem doing something like this (or even recommending it to a supervisor if Perl 6 were being considered), but I can picture a lot of people grumbling if Larry were to mandate it as The Way Forward.

Again, I support a move like this that would separate the binary names. It would make the whole "How do we decide if it's Perl 5 or 6?" question moot. It's the masses that I imagine are (or would be) opposed to the idea that are keeping us in this mess.
