================================================================================================
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 2021.06.108.g.123046.c.75 built on MoarVM version 2021.06.384.g.40.f.08.dcf.0,
running on linuxmint (20.Ulyana) / linux
