================================================================================================
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.
Valgrind options can be added with MVM_VALGRIND_OPTS environment variable.

This Rakudo version is 2019.03.1.638.g.887121991 built on MoarVM version 2019.05.86.g.638001351,
running on ubuntu (19.04.Disco.Dingo) / linux (17.Ubuntu.SMP.Wed.May.15.10.52.21.UTC.2019)
