Moe is interesting, but in a recent interview I saw, it wouldn’t become “Perl that is less messy than Perl”, although that had been my first impression when it was first announced.

It would indeed be a really interesting experiment to create something that’s compatible with most non-abusive uses of p5, but is better defined and cleaner on the inside.

      I’m afraid that anything that’s part of p6 doesn’t fall under the “I could actually USE right now” category :)

        (Rewritten to be more useful for folk reading this comment out of its original context.)

        use v5 is a new (started April 2013) project aiming to build a P5 reimplementation.

        It builds on Rakudo/NQP, a new open source compiler/ast/vm toolchain used to implement Perl 6.

        Apart from writing "use v5;" at the top of files, using v5 doesn't require that you write or read any Perl 6 code. You just write Perl 5 code and run it. Results will of course depend on how far the project has progressed.

        v5's current goal is to pass as much of the non-XS parts of the p5p perl 5 test suite as possible. It will likely take years to achieve substantial coverage, assuming it one day does. At the time of writing this comment it's passing 1,000 or so of the 40,000 or so tests in the suite. See STATUS for the current passcount.

        The host compiler toolchain includes a backend which is slated to embed libperl and support use of existing XS modules. It's not clear to what degree, if any, v5 can or will be able to make use of this to extend its utility to cover scenarios involving use of XS modules.

        The v5 project builds on parsing features (grammars) and a parser (STD) designed by Larry Wall.

        For more info watch this 20 minute video or view the v5 github repo or the use v5 blog or visit the IRC channel #perl6 on freenode.
