For <span class="bold"><strong>icl</strong></span> containers the single <code class="computeroutput"><span class="identifier">size</span></code> function known from std containers
branches into tree to five different members functions. The table above shows
the types, <code class="computeroutput"><span class="identifier">size</span></code> functions

Linear complexities <span class="emphasis"><em>O(n)</em></span> refer to the container's <code class="computeroutput"><span class="identifier">iterative_size</span></code>:
