Thanks. I've found a less invasive solution =E2=80=93 to= name all inner functions witu tmp/=E2=80=A6 prefix, and unset them with ns= et -f -m tmp/\*

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 () {
=C2=A0 trap "print FROM INNER: \$0; trap 'print FROM OUTER: \$0= 9; EXIT" EXIT
}
outer () {
=C2=A0 inner
}

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


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