Listed below are all of the tasks on Rosetta Code which have been solved using Perl 6.

Perl 6 is the up-and-coming little sister to Perl 5. Though it resembles previous versions of Perl to no small degree, Perl 6 is substantially a new language; by design, it isn't backwards-compatible with Perl 5. In development since 2000, Perl 6 still lacks a complete implementation of its specification, the Synopses. However, the Rakudo implementation is getting close to that goal.

Damian Conway described the basic philosophy of Perl 6 as follows:

The Perl 6 design process is about keeping what works in Perl 5, fixing what doesn't, and adding what's missing. That means there will be a few fundamental changes to the language, a large number of extensions to existing features, and a handful of completely new ideas. These modifications, enhancements, and innovations will work together to make the future Perl even more insanely great -- without, we hope, making it even more greatly insane.

Major new features include multiple dispatch, declarative classes, grammars, formal parameters to subroutines, type constraints on variables, lazy evaluation, junctions, meta-operators, and the ability to change Perl's syntax at will with macros and user-defined operators.

There are several different implementations of Perl 6. They vary widely in design goals, degree of completeness, and current development activity. At present, the implementations closest to matching the specification are Pugs, written in Haskell, and Rakudo, built on the Parrot virtual machine; of these, only the latter is actively developed. There are also active efforts to port to .NET and other platforms.
