================================================================================================
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 2017.01.204.g.266.f.34571 built on MoarVM version 2017.01.47.g.01570074,
running on arch (4.9.3.1.arch) / linux (4.9.7.1.ARCH)
