# original by Guss: https://askubuntu.com/a/1386907
# improvements: syntax cleanup, shellcheck-linted, cyclic menu selection, compatible with `set -e`
#
# example usage:
#   apples=("Red Delicious" "Granny" "Cosmic Crisp")
#   choose_from_menu "Select an apple:" chosen "${apples[@]}"
#   echo "You chose: $chosen"
function choose_from_menu() {
	local -r prompt="$1" outvar="$2" options=("${@:3}")
