<p>
set is an <a href="../sequence/concepts/associative_sequence.html" title="Associative
Sequence">Associative
Sequence</a> of heteregenous typed data elements. Type identity is used
to impose an equivalence relation on keys. The element's type is its key.
A set may contain at most one element for each key. Membership testing and
element key lookup has constant runtime complexity (see <a href="../notes.html#fusion.notes.overloaded_functions">Overloaded
Functions</a>).

<p>
The variadic class interface accepts <tt class="computeroutput"><span class="number">0</span></tt>
to <tt class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></tt> elements,
where <tt class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></tt>
is a user definable predefined maximum that defaults to <tt class="computeroutput"><span class="number">10</span></tt>.
Example:
</p>
<pre class="programlisting">
<span class="identifier">set</span><span class="special">&lt;</span><span class="keyword">int</span><span class="special">,</span> <span class="keyword">char</span><span class="special">,</span> <span class="keyword">double</span><span class="special">&gt;</span>
</pre>
<p>
You may define the preprocessor constant <tt class="computeroutput"><span class="identifier">FUSION_MAX_SET_SIZE</span></tt>
before including any Fusion header to change the default. Example:
</p>
<pre class="programlisting">
<span class="preprocessor">#define</span> <span class="identifier">FUSION_MAX_SET_SIZE</span> <span class="number">20</span>
