Run the whole script from my original email. Maybe I managed to trip
bash up with something I edited out of the last email. Pay particular
attention to var_3.

#!/usr/bin/env bash

func_1 () {
  local var_1='BREAD'
  local var_2='ICE CREAM'
  local var_3='EGG'
  func_2
  printf '%s\n' "func_1:"
  local -p var_1
  local -p var_2
  local -p var_3
}

func_2 () {
  local -n nameref_1=var_1
  local -l nameref_1
  nameref_1='TOAST'
  local -nl nameref_2='VAR_2'
  nameref_2='MILKSHAKE'
  local -n nameref_3='var_3'
  nameref_3='soufflé'
  local var_4='GROUND BEEF'
  local -n nameref_4='var_4'
  local -l nameref_4
  printf '%s\n' "func_2:"
  local -p nameref_1
  local -p var_1
  local -p nameref_2
  local -p var_2
  local -p nameref_3
  local -p var_3
  local -p nameref_4
  local -p var_4
}
