================================================================================================
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 2016.12.10.g.7.a.642.f.8 built on MoarVM version 2016.12,
running on debian (8.jessie) / linux (4.8.14.moby)

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