================================================================================================
This is Rakudo 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 2020.02.1.308.g.1.a.10.b.63 built on MoarVM version 2020.02.1.71.g.1.bd.5.f.19,
running on linuxmint (18.3.Sylvia) / linux
