You're at an advantage.

You bless to get an object in perl5, well, there's a default "thing" that well bless for you. You can use bless yourself. There, you know something about perl6 in the language you already know. It's just augmented. The culture is still there. If you know Moose, some things will be quite familiar. There's still, "my", strict is enforced by default etc.

ipv6? Longer ips with segmentation so you can form your own assignments in house.

Html5? html4 + new stuff. You have some new tags. You know half this stuff already. The a tag may have changed, I don't know, but if it has, I'm sure I'll learn it quickly enough over time.

Make some mistakes while learning this stuff. Everyone will. Some people are already experts because they are designing it or want to be involved so early on. Or both. Chances are, your mistakes will teach how some things are done wrong. The feedback loop continues.

And hell, if you learn some perl6, some html5 and some ipv6 by year end, you'll probably be on the far side of the bell curve. Jump in! The water isn't fine just yet. :D
