Unclear what side-effect messing about with localtraps may have on
this, but you can use one EXIT trap to set another EXIT trap:

inner () {
  trap "print FROM INNER: \$0; trap 'print FROM OUTER: \$0' EXIT" EXIT
}
outer () {
  inner
}

% outer
FROM INNER: outer
FROM OUTER: Src/zsh


Getting the quoting right for something more complicated, is left as
an exercise.
