Booking.com employee and Perl core hacker Flávio Glock (fglock) was interviewed about Perlito (github), a piece of software that can compile Perl5 or Perl6 to other languages, including Javascript! Meaning you can run Perl in the browser!

You can test the JS version here: http://perlcabal.org/~fglock/perlito5.html
Flávio’s giving a talk about Perlito at Booking offices in Amsterdam on the evening of October 29… it sounds like it’ll be an interesting talk!
