================================================================================================
This is Rakudo Perl 6 running in valgrind, a tool for debugging and profiling programs.
Running a program in valgrind usually takes *a lot* more time than running it directly,
so please be patient.
This Rakudo version is 2016.11.134.gb.96.bf.5.bd.0 built on MoarVM version 2016.11.25.g.4.be.6.b.384,
running on ubuntu (14.04.3.LTS.Trusty.Tahr) / linux (3.19.0.32.generic)
