Re: How to have Perl 5 and Perl 6 cohabitate nicely on CPAN

Agreed, but you know you're going to see this and variants thereof: requires: perl: 6,0 Should that be a rejection for unknown format? I would think so. Better to fail early than have junk spread throughout the CPAN.

Using a directory perl6/ and controlling that via PAUSE seems a bit more reliable and consistent than expecting users to use a particular convention not to confuse files. We also thought that it might be relatively easy for to add radio-boxes to the PAUSE upload page to indicate Perl 5 or Perl 6 and to place Perl 6 distributions into the proper directory without it having to be specified explicitly. (Whether it *must* be specified as one or the other, which would require updates to Perl 5 tools like CPAN::Uploader I will defer to Andreas' judgment.) No need for a radio-box if PAUSE auto-detects from the META file. I think there are arguments both for and against. For example what to do if PAUSE cannot detect ? Graham.

Using a directory perl6/ and controlling that via PAUSE seems a bit more reliable and consistent than expecting users to use a particular convention not to confuse files. I remember bringing this up in one of the panel discussions at OSCON following the decision to go with Perl6 as it will prove to be problematic, especially given the limitations in the namespace, and I think they will need to be very separate. I haven't kept up with P6 development and the module conventions, but I had thought this particular issue had been solved with requiring 'Perl6::' or something similar to distinguish P5 from P6 modules. Briefly looking at the P6 synopsis for CPAN ( http://perlcabal.org/syn/S22.html ) still gives me the impression that there will be a version prefix and that cpan6 is still in development, both of which still seem like very good ideas. We also thought that it might be relatively easy for to add radio-boxes to the PAUSE upload page to indicate Perl 5 or Perl 6 and to place Perl 6 distributions into the proper directory without it having to be specified explicitly.

No need for a radio-box if PAUSE auto-detects from the META file. I think there are arguments both for and against. For example what to do if PAUSE cannot detect ? In a post-P6 world, I'd say if it can't be detected, it should be rejected since it will be an important, if not essential, piece of information for PAUSE. e.

* Adam Kennedy a...@ali.as [2010-04-14T20:53:15] Alternative option, when we switch to Perl 6 also take the opportunity to switch to a specific named extension. D/DA/DAGOLDEN/Foo-Bar-1.23.c6z I haven't wanted to get into this thread, but I will say that I had the same idea as Adam, and didn't think it was crazy. -- rjbs
