The best part of Perl 6 is "Perl 6 Rules"<http://en.wikipedia.org/wiki/Perl_6_rules>, a "PEG"<http://en.wikipedia.org/wiki/Parsing_expression_grammar> parsing language and a replacement for Perl 5 regular expressions. It is a simple and readable way to define new languages, including Perl 6 itself.

"Ingy döt Net"<http://ingy.net/> has taken the best ideas from Perl 6 Rules and created an "Acmeist"<http://acmeism.org/> parsing language called "Pegex"<http://www.pegex.org/>. Pegex can be used to define new languages that work the same in Perl, Python, Ruby, JavaScript and any other languages that support Pegex.

In this talk, Ingy will show you how to use Pegex in Perl, as simply as using a regex. He'll also demonstrate how he is using Pegex as the basis of his Acmeist projects like "YAML"<http://yaml.org/>, "TestML"<http://testml.org/>, "JSYNC"<http://jsync.org/> and "C'Dent"<http://cdent.org/>.

TestML - Write Once, Test Everywhere

When you write "Acmeist"<http://acmeism.org/> software you need to make sure
it passes the same tests in many different programming languages. When you
write modules that you want to publish in Perl 5 and Perl 6, the same truth
applies.

"TestML"<http://testml.org/> is a new Unit Testing language that runs the same
tests in Perl 5, Perl 6, Python, Ruby, JavaScript and many other modern
programming languages. It makes writing tests so nice and simple, that you

Gloom and Mousse (lightning talk)

Moose is the Swiss Army Forest Animal solution for Perl OO, but there are many places
where a Moose won't fit.

What if you could write object oriented modules for CPAN, and get the OO for FREE?

Now you can!
