*     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
*     var date2 = new Date(1234567890000);
*     date1.valueOf(); // 1234567890000
*     assert( date1 !== date2 );
*     assert( Immutable.is( date1, date2 ) );
*
* Note: overriding `valueOf` may have other implications if you use this object
* where JavaScript expects a primitive, such as implicit string coercion.
