You make it sound like "syntactic sugar" is an insult, which it isn't. I wasn't going Luddite, I was merely pointing out that "Modern Perl" comes with a price tag; it can be quite hefty for some applications and may be worth additional consideration.

You're arguing the software developer side of equation, and of quite advanced hacker, too. I agree that new features can make a developer more productive, but what I'm saying is that it's not given. How many people out there are using this interesting stuff in their day-to-day work? I don't, so I can't run a performance comparison for it. I ran tests for what I do use, and it shows me that even with the latest Perl release my DBD::SQLite application shows 17% performance hit compared to 5.8.9. Does that matter? For me, it does a lot.

As for your examples, I don't see anything ground-shaking there. Module installer was there for ages, CPAN.pm is working fine for me thanks. Support I have never needed, and if I need security I will buy commercial support anyway. Lots of bug fixes were supposedly backported to 5.8.9 which was released after 5.10 - and how many of later fixes are for later bugs? Unicode is one major advantage, sure, but I don't need it, usually - and considering tchrist's latest musings on stackoverflow, I'd screw it up anyway. So, do I really gain something visible with Modern Perl? Yeah, performance hit. All new features are potential good, but slower execution is here for every existing script and module, every time I run them. Are you ready to dismiss this easily in favor of newer features? I don't.

In short, I don't think that "Modern Perl is better for everyone" is true.

That said, I do wish for a magical combination of Modern Perl features and Legacy Perl speed...

Regards,
Alex.
