In the ancient Ruby, symbols are represented by integers. In that era, to get string representation from integers, we used `Integer#id2sym` method. Later, `Symbol` was introduced, and `id2sym` was used for compatibility. Today, no one uses `id2sym` any longer. It is described in ISO 30170:2012 standard but I consider it as a mistake.
