Cultured Perl: Perl 6 grammars and regular expressions: "For any Perl programmer, the Perl 6 project is a hot topic. Perl has
always been an evolving language, and Perl 6 has definitely evolved
from Perl 5 in almost every way imaginable (but you can still tell they
come from the same camel). Perl 6 will run on top of Parrot, a
versatile virtual machine that will be able to load and interpret not
only Perl 6 bytecode, but many other languages as well."
