The ``++IEquatable<T>++`` interface has only one method in it: ``++Equals(<T>)++``. If you've already written ``++Equals(T)++``, there's no reason not to explicitly implement ``++IEquatable<T>++``. Doing so expands the utility of your class by allowing it to be used where an ``++IEquatable++`` is called for.

**Note**: Classes that implement ``++IEquatable<T>++`` should also be ``++sealed++``.

{
