+1 for that, though all the ideas have been good.

You may also want to play with $PS4 which is the prompt for the -x debug 
output.

Possibly overkill example (and this looks like negative line numbers 
when not in a function):
	export PS4+xtrace $BASH_SOURCE::$FUNCNAME-$LINENO:= '

NOTE that the first character is duplicated to indicate nesting level, 
so make sure it's something that makes sense, like "+".

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
