I honestly fear it may already be too late for perl6.
Let's just look at this like any other software development project. Perl 6 may well be heads and tails above Perl 5, or even other languages, but it has seriously lost momentum to other languages.
It is good to have a roadmap, and good to change, but they should have settled on like the top 5 features that they really wanted, come up with a solution for it, and released it. At this point, they're just in a cycle of taking so long that the innovation curve is out pacing their development curve and they keep holding back.
Perhaps they became oversensitive to the criticism that perl wasn't cutting edge enough and so tried to chase some line of purity that would shut everyone up forever, but it has turned it into a death march. Personally, just a few improvements like ditching the sigils and some performance enchancements would have been worth a major version upgrade to me.
Perl is still relevant only because of the code that already exists in it, and the people who know it. The longer they take to end the uncertainty of perl6, the more people will become comfortable with other languages which are new or have moved on, and the less code there will be in perl, relative to other projects.
I like perl and I have been waiting for Perl 6 to take off, but at this point, I don't know what I would do with it other than piss off people who are using ruby or python or something else to so sysadmin/DevOps work. If I have to learn to be as good at ruby or python as I am with perl, I'm not going to bother with perl any more.
