+ * An extension of the "same-value" algorithm as [described for use by ES6 Map
+ * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
+ *
+ * NaN is considered the same as NaN, however -0 and 0 are considered the same
+ * value, which is different from the algorithm described by
+ * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
+ *
+ * This is extended further to allow Objects to describe the values they
+ * represent, by way of `valueOf` or `equals` (and `hashCode`).
+ *
+ * Note: because of this extension, the key equality of Immutable.Map and the
+ * value equality of Immutable.Set will differ from ES6 Map and Set.
+ *
+ * ### Defining custom values
+ *
+ * The easiest way to describe the value an object represents is by implementing
+ * `valueOf`. For example, `Date` represents a value by returning a unix
+ * timestamp for `valueOf`:
+ *
+ * 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.
+ *
+ * For more complex types, especially collections, implementing `valueOf` may
+ * not be performant. An alternative is to implement `equals` and `hashCode`.
+ *
+ * `equals` takes another object, presumably of similar type, and returns true
+ * if the it is equal. Equality is symmetrical, so the same result should be
+ * returned if this and the argument are flipped.
+ *
+ * assert( a.equals(b) === b.equals(a) );
+ *
+ * `hashCode` returns a 32bit integer number representing the object which will
+ * be used to determine how to store the value object in a Map or Set. You must
+ * provide both or neither methods, one must not exist without the other.
+ *
+ * Also, an important relationship between these methods must be upheld: if two
+ * values are equal, they *must* return the same hashCode. If the values are not
+ * equal, they might have the same hashCode; this is called a hash collision,
+ * and while undesirable for performance reasons, it is acceptable.
+ *
+ * if (a.equals(b)) {
+ * assert( a.hashCode() === b.hashCode() );
+ * }
+ *
+ * All Immutable collections implement `equals` and `hashCode`.
+ *
