Perl 6 on MoarVM has had a JIT for a few years
Dear readers, I recently came across the following comment on the internet (via Perl 6 weekly ): perl6 on MoarVM is starting to grow a JIT Which is very interesting because: Someone had at least heard of our efforts, so that's a win. But they had left with the impression that it was still in a beginning phase. Clearly, we have some PR work to do. Consider this my attempt.
