Yes, I provide some programming work for a couple non-profits that run perl 5.8 and perl 5.10 respectively. As a consequence, I don't always get to utilize the latest and greatest.

And even though the 5.10 EOL was announced, I find that a lot of posters aren't always on a current version of perl. Therefore sometimes it's easier to just assume they don't have access to certain features.

I definitely appreciate the \K marker though, and use it plenty now to clean up regex's when I can.
