in reply to Why no one port perl5 to Parrot?

parrot is currently too slow to be an efficient competitor, there's not much progress, and there was heavy mismanagement. Feature-wise it is an interesting alternative.

But there is a lot going on.

Larry is already writing a p5 grammer for perl6/nqp, and had with MAD a working src-level translator.
Flavio Glock has with perlito a src level translator and compiler already.

perl6 is quite perl5 compatible, with much more features and better performance than perl5 for complicated use-cases, which you would call "Modern Perl" (i.e. Moose, Grammars, ...). But it is totally post-modern perl.

perl11.org (5+6=11) is an umbrella project to try to mix/replace the various parts, parser, compiler/optimizer, runtime. See irc.perl.org #perl11

I am thinking of an implementation based on vmkit to replace parrot or write a better p5 vm, codename p2.

rakudo is working into similar directions, making nqp on jvm or mono or whatever possible.

Perl5 XS is not that big a deal. Either throw it away as it is inefficient and hard to work with anyway. Or provide convenience wrappers. Better languages provide better glue interfaces. Inline e.g. is much better, but you still have to deal with the XS API.

    All true and instructive.

    One might also mention that Perl6 is specified to be able to include some Perl5 code with the 'use v5 {}' construct. This means that eventually Perl5 will be ported to parrot, at least via the rakudo implementation of Perl6.

    We just have to be patient.

    Very interesting, Is this work there somewhere on the internet or Larry is still developing it in private.

    I am thinking of an implementation based on vmkit to replace parrot or write a better p5 vm, codename p2.

    Again is this work there some where on the internet.

        I do not believe Larry has lost interest. He's just a busy guy, mostly focused on helping get Perl 6 to 6.0.0, writing his new Perl 6 book, and so on. Here's the most recent exchange I'm aware of with Larry Wall about MAD. Also, as noted in the p5p email exchange Reini linked, "we've been asked by Larry not to actually purge them from the source".
