 on the <tt>reference</tt> type. Assume that <tt>b</tt>
is an instance of <tt>dynamic_bitset</tt>, <tt>i, j</tt> are of
<tt>size_type</tt> and in the range <tt>[0,b.size())</tt>. Also,
note that when we write <tt>b[i]</tt> we mean an object of type
<tt>reference</tt> that was initialized from <tt>b[i]</tt>. The
variable <tt>x</tt> is a <tt>bool</tt>.</p>
