* ==== User-Defined \Hash Keys
*
* To be useable as a \Hash key, objects must implement the methods <code>hash</code> and <code>eql?</code>.
* Note: this requirement does not apply if the \Hash uses #compare_by_id since comparison will then rely on
* the keys' object id instead of <code>hash</code> and <code>eql?</code>.
* Note: this requirement does not apply if the \Hash uses #compare_by_identity since comparison will then

* \Object defines basic implementation for <code>hash</code> and <code>eq?</code> that makes each object
* a distinct key. Typically, user-defined classes will want to override these methods to provide meaningful
