| This is Rakudo Perl 6 running in the GNU 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 2017.09.92.g.8.cf.083.c.70 built on MoarVM version 2017.09.1.32.g.9749.b.0.fa.1, | |
| running on ubuntu (14.04.3.LTS.Trusty.Tahr) / linux (3.19.0.32.generic) | |
| Type `bt full` to generate a backtrace if applicable, type `q` to quit or `help` for help. | |
