<h2><font color="#009999">20.6 Private Inheritance and
	Names</font></h2>
<font size="+1">

<ul>
	<li>Inheritance normally implies an "is-a" relationship
		<ul>
			<li><i>Substitution principle</i>:  If <tt>B</tt> inherits from
				<tt>A</tt>, then <tt>B</tt> can be used wherever <tt>A</tt> is
				expected</li>
			<li>Interface for the base class becomes a basis for the i/f for the
				derived class</li>
		</ul>
	</li>
	<li>We occasionally use inheritance even when the "is-a" relationship
		doesn't hold (see example)
		<ul>
			<li>A solution is to declare that <tt>Set</tt> inherits privately from
				<tt>List</tt></li>
			<li>With <i>private inheritance</i> all inherited attributes become
				private in the derived class</li>
			<li>The base class' interface does not flow through to the derived
				class</li>
		</ul>
	</li>
</ul>
