Perl 5.14 should be out in early 2011, making it the second major version on the new release schedule. Once 5.16 comes out in 2012, I think we'll officially be in a new era of Perl 5.

It is a great pleasure that my 4 hour hack last night lets me now introduce: Sunaba the perl sandbox environment to run any PSGI/Plack applications.

After about two weeks of development, this is a reasonably functional CPAN client with just a fraction of the overhead, complexity and verbosity of the CPAN and CPANPLUS clients that come with the Perl core. via www.dagolde

"Nijinsky" is difficult to spell. Also in different countries, Russian names are spelt differently (Niżyński, Nizhinskiy etc.). I also thought of "Kirin", but there's the beer...
