Oh, that is a long and complicated story.

Perl 6 was announced a long time ago, but it took many years of development and planning and I (like others) used to joke that Duke Nukem Forever was going to be written in Perl 6. And then we got egg on our face when Duke Nukem Forever was released first. (And it turned out to be a turkey).

However, many clients I spoke to at that time were telling me they wouldn't upgrade their Perl code because they were waiting for the new version ... which was seemingly never going to arrive. Worse, it became clear that Perl 6 was a new language, with common roots, but it wasn't like the Python 2/3 split: a wholesale rewrite of code would be necessary, or try to use a Perl 5 compatibility mode that may or may not have proven useful.

So companies weren't upgrading, Perl developers were fighting, people were leaving the community and the Osborne Effect (https://en.wikipedia.org/wiki/Osborne_effect) could be renamed the Perl 6 Effect (I'm aware that the Osborne Effect is more complicated than it's often portrayed).

Worse, Perl 5 couldn't upgrade to Perl 6 because that version number was taken. Perl looked, to the outside world, like it wasn't upgrading any more. I even had one guy screaming at me at a Linux Conference about how Perl is shit, hadn't updated in 20 years, and ticked off a bunch of "facts" about Perl, most of which were objectively incorrect at the time, but Perl could no longer get its message out.

There was discussion about leap-frogging the version number and going straight for Perl 7, but that caused even more fights, more people dropping out of the community, and we fractured. We tried saying "the name of the language is Perl 5 and we're upgrading every year—we're currently on version 34—but that didn't satisfy anyone, either.

Eventually, Perl 6 was renamed to Raku (http://blogs.perl.org/users/ovid/2019/10/larry-has-approved-...) and that freed us to upgrade our version number, but to what? Sawyer X, the former Perl Pumpking (development manager) proposed the Perl 7 project, but for many reasons, that also caused much anger.

So today, we have Perl. There are ideas of moving to Perl 7, but much work needs to be done. My Corinna OOP project is likely part of that work and the Perl Steering Committee has met with me to say they'd like Corinna in core, but slowly, step-by-step, to ensure that we don't push too much into the core and make mistakes we can't easily back out of.

I have more ideas about what is needed to get to Perl 7, but they'll largely wait until after Corinna is in core and fleshed out. It's a lot of work and the team working on Corinna (making great suggestions and also helping me not make boneheaded errors), have put in a lot of effort to create something we can turn into a proper RFC. Paul Evan's Object::Pad (https://metacpan.org/pod/Object::Pad) is a testbed for many of these ideas.

So, we're getting there, but slowly. However, it appears to be moving along more smoothly than other efforts in the past. The fact that the goal is more modest helps.

Thank you for your detailed explanation. I think this would be worthy of an HN submission of its own.

Also, I'd prefer a language with slow incremental changes because it eases the maintenance burden.
