This is Rakudo Perl 6 running in the  debugger, which often allows the user to generate useful back-
traces to debug or report issues in Rakudo, the MoarVM backend or the currently running code.

This Rakudo version is 2019.07.1.172.g.23.cfe.1.c built on MoarVM version 2019.07.1.80.g.24.e.2986,
running on linuxmint (18.3.Sylvia) / linux (42.16.04.1.Ubuntu.SMP.Tue.Oct.10.16.32.20.UTC.2017)

Type `bt full` to generate a backtrace if applicable, type `q` to quit or `help` for help.
