For me it comes down to a couple questions. And I've got a feel that these are some of the actual questions many people are looking for answers for:
- When will Perl 6.0(.0) be stabilized?
- Which Perl 6.(* + 1, 2, ...) is expected to not break Perl 6.*
- When will the developers of the spec consider it stable enough to value back-compatibility and/or ease of upgrade over progress?
- When's Rakudo expected to catch up with the former?
- Will I be able to use the CPAN?
- When will I be able to use the CPAN, and how much of it?
Personally, I think I know many of the answers, but they're probably outdated because I'll personally probably be on Perl 5 unless there's either a strong access to CPAN or CPAN like functionality, or Perl 6.* is stable enough for casually writing CPAN modules without frequent breakuppage.
So, in essence, people might say "Perl 6" and not "Perl 6.0.0," because they don't know the planned versioning scheme for the specification, or the version of the specification that is planned for the above language criteria.
