  3. This is Rakudo Perl 6 running in the debugger, which often allows the user to generate useful back-
  4. traces to debug or report issues in Rakudo, the MoarVM backend or the currently running code.
  5.  
  6. This Rakudo version is 2019.03.1.673.gcf.6.f.6.d.9 built on MoarVM version 2019.05.96.gd.6.f.9.e.02,
  7. running on linuxmint (18.3.Sylvia) / linux (42.16.04.1.Ubuntu.SMP.Tue.Oct.10.16.32.20.UTC.2017)
