I guess I don't see why that's an important question when:
- there's no horizon on which a complete implementation (or stable target for a spec/test suite, for that matter) is promising to arrive
- 5.x has demonstrated it's a living/growing branch with as much a future as any open source project
- By comparison, for something like Python, the concrete reality of having a plan for changing horses midstream seems to be more painful than just keeping on with Perl 5
Or are those false assumptions?
I don't really expect everyone to keep up with everything about Perl. I'd certainly had no idea 5.10 was even a glimmer in someone's eye for over a year after it had come out because I was busy with front-end work and PHP projects. And I'm responding partly because maybe I've missed something again and this is a learning opportunity.
At the same time, when someone speaks up as the GP did and asserts that technical decision makers have done their homework and picked things like Python or Java by comparison to insulate themselves from the spectre of version shifts and associated porting costs, I think they may have earned themselves a challenge.
