Yes. v5, a Perl 5 compiler written in Perl 6, is promising tech with potentially huge long term (10 years) strategic consequences for Perl 5 and Perl. But it's very early days and it correctly handles only the simplest of modules. I'd hazard a guess that currently less than 1% of CPAN modules pass their tests when loaded by v5.

But Inline::Perl5 is a completely different animal. It handles modules using XS or whatever fine. See my nearby comments for further details.
