 * @assertion Object decode(String str, {reviver(key, value)})
 * The optional reviver function is called once for each object or list property
 * that has been parsed during decoding.
 * The key argument is either the integer list index for a list property,
 * the map string for object properties, or null for the final result.
 * The default reviver (when not provided) is the identity function.
 * @description Checks that reviver function, if provided, is called at least
 * once for each object or list property parsed.
