Frankly, If had what it takes to work on a compiler I would have give my full free time apart from my day job to Perl 6. I generally browse through the commits and irc logs on a frequent basis. From what looks clear is with the Current pace we are set for an early 2015 or 2014 production release. That date would be a lot more nearer if pmichaud didn't had personal problems. But given what he is going through, I would call him a hero.
Else, we would have had Perl 6 out by around mid 2013.
Well, I do have have some personal opinions about the current state. Especially running Perl 6 on multiple backends. I think our primary focus should be on having a feature complete stable compiler on atleast one backend first. Then we we can go on to other backends.
Coming to productivity of hackers per se, Perl 6 has had the luxury to get some very dedicated hardworking hackers. Audrey, Jonathan, Larry, Patrick, Moritz, Masak, Stephan are all great people. You can't really expect more from them.
Its just that these health related issues are bugging our people time to time and some petty distractions let to all this delay. I hope everything goes fine and we have a great compiler out by 2015 atleast.
