- *  Equality---At the <code>Object</code> level, <code>==</code> returns
- *  <code>true</code> only if <i>obj</i> and <i>other</i> are the
- *  same object. Typically, this method is overridden in descendant
- *  classes to provide class-specific meaning.
- *
- *  Unlike <code>==</code>, the <code>equal?</code> method should never be
- *  overridden by subclasses: it is used to determine object identity
- *  (that is, <code>a.equal?(b)</code> iff <code>a</code> is the same
- *  object as <code>b</code>).
- *
- *  The <code>eql?</code> method returns <code>true</code> if
- *  <i>obj</i> and <i>anObject</i> have the same value. Used by
- *  <code>Hash</code> to test members for equality.  For objects of
- *  class <code>Object</code>, <code>eql?</code> is synonymous with
- *  <code>==</code>. Subclasses normally continue this tradition, but
- *  there are exceptions. <code>Numeric</code> types, for example,
- *  perform type conversion across <code>==</code>, but not across
- *  <code>eql?</code>, so:
- *
- *     1 == 1.0     #=> true
- *     1.eql? 1.0   #=> false
