Perl has taken another step on the path to 5.10 with the release of 5.9.4. The most fun new feature, as far as I'm concerned looks to be state variables. Read pod/perl594delta.pod in perl.git for more on that, and other new things since 5.9.3. (There is no release announcement yet, so I'm not linking to it.)
Update: Er, yes, there is a release announcement, and this is apparently old news.
Update: Typo fix, thanks, McDarren
