So. What. Is. The. Problem.

It is.  You can verify this trivially.

       ("-w"|"--warning")
         case "$2" in
           (+([[:digit:]])) 
             local warn="$2"
             shift 2
             ;;
           (*) 
+            printf 'warned!\n' >&2
             local warn="1"
             shift 2
             ;;
           esac
           declare -i local f=1
           ;;
