This is Rakudo 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 2021.12 built on MoarVM version 2021.12,
running on linuxmint (20.Ulyana) / linux

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