Great questions! You are correct, there is an issue with Perl 6 blocking progress and P5P Pumpkings also blocking progress. Saint Larry says we can have no Perl 7 until Perl 6 is finished, which may be never!
Perl 11 is a philosophy, specifically the idea that we can re-unify Perl 5 and Perl 6 if we are able to make Perl pluggable at the 3 main levels of grammar/parser, compiler/bytecode, and VM/interpreter/runtime. Perl 11 is not an actual software product itself, and Perl 11 is not an actual version of Perl. (Yet.) There are multiple projects that fall under the Perl 11 umbrella, many of which are listed on the Perl 11 website. I'm currently working on a more exhaustive comparison table for ALL Perl projects, and I'm already up to 37 of them!
P2 is Reini Urban's software project to build a new JIT runtime for both Perl 5 and Perl 6 using the pre-existing Potion VM. The "2" in "P2" comes from adding together the two "1" digits in "Perl 11". :-)
RPerl is my software project to build a Perl-to-C optimizing compiler for low-magic Perl 5 code. RPerl is very different than P2, in that RPerl is focused on high-speed and low-magic Perl 5 only. Also, RPerl uses the existing Perl 5 code, and P2 is totally new and different than the existing Perl 5.
There are also several other Perl 11 projects, you may wish to read more about them at the Perl 11 website.
Did I answer your questions? Will you please consider making a generous pledge to support RPerl development?
