================================================================================================
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 2016.04.126.g.2.b.74.c.90 built on MoarVM version
2016.04,
running on ubuntu (14.04.2.LTS.Trusty.Tahr) / linux (3.13.0.37.generic)

...I feel like I needed to specify some option(s) to get something more
useful out of that; the addresses by themselves are less than useful. :/
