This highlights the "don't print set +x" trick from https://stackoverflow.com/a/19226038

Using set -x ensures a command is printed with any spaces and special characters properly escaped. I frequently don't want every interpreted step to be printed, e.g. conditionals and loops, hence a per-command "echo-eval" wrapper function
