When you say "no more <insert foo syntax here>" do you mean these things are no longer supported, as in, existing code will break?

That's kind of what it sounds like you're saying. However, I think it's not what you mean.

While the intended meaning may be obvious to me and to most of us, there are a lot of redditors here today reading this, some of whom are going to think "holy crap, Perl sure breaks a lot of stuff when it moves forward in a dot release." Maybe a bit of clarification would be nice on what breaks and what doesn't.

Thanks for the great post! I'm looking forward to using these features.
