Hi William,
when it fails or hangs it doesn't print the last line.
Please check attached file for output of the stack.
Since the failures are random, it's easier to invoke it in a loop:
bash$ for i in $(seq 100); do raku test.raku; done
If nothing is wrong with the code, i'll open a bug in the github.
Regards,
David Santiago
