It may not be perfect, but it helps in many situations. I set a debug flag in my main script (often passed as a script argument, e.g., myscript -d). That flag can be checked in loops and/or passed to functions. If the flag is set I then execute set -x or whichever form is desired. This way I have a form of debugging built into the script at all times, but it has little impact production usage.
