When I now read that Damian Conway (and maybe others) want Perl 6 modules on CPAN...
If you've read that, then I have been either misquoted, misattributed, or misunderstood.
I want Perl 6 modules on 6PAN, or C6AN, or CPAN6, or some other suitable parallel to CPAN. At the moment, that repository seems to be named "GitHub", but I still long for a more PAUSE/CPAN-ish front end to it.
I certainly don't want Perl 5 and Perl 6 on a single undifferentiated repository. Half of the Perl 6 modules I've written are direct ports of my existing Perl 5 modules, with identical names and similar APIs. There is no way they can coexist with Perl 5 modules...at least, not under CPAN's linear notion of "latest version" (which, BTW, I wholeheartedly approve of as being much more appropriate for the majority of CPAN users).
