I still use Perl 5.8.8 because it's default in my OS (Debian Etch). I have a 5.10.0-built laying around for testing, and one of my computers is already upgraded to Debian Lenny (which also uses 5.10.0).

So most likely my switch to 5.10.0 is coupled with the release of Debian Lenny.

(BTW the 5.8.8 to 5.10.0 transition went without any problems, except that I had to rebuild some of my self-made debian packages. Thanks to all the Debian Perl Maintainer!)

I already want to write say $x each time I'm actually writing print $x, $/ or print "$x\n"; now.
