This is a demostrator for golang/go#69625 and jfreymuth/pulse#40.
It uses jfreymuth/pulse and my own patrix and digimodes libraries to play a sentece in
morse code. The time package is not used directly, but maybe somewhere in the libraries.
The panic occurs after a random time, usually in under one minute. Please be patient.

This is the full stacktrace of one execution.
