================================================================================================
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 2017.06.231.g.8.d.5.f.3324.a built on MoarVM version 2017.06.82.g.2.e.683.f.95,
running on arch (4.11.3.1.arch) / linux (4.11.9.1.ARCH)
