<p>If <code>len</code> is &lt; 0 or <code>pos</code> exceeds <code>this</code>.length, an empty Array [] is
returned and <code>this</code> Array is unchanged.</p>
<p>If <code>pos</code> is negative, its value is calculated from the end    of <code>this</code>
Array by <code>this.<a href="#length">length</a> + pos</code>. If this yields a negative value, 0 is
used instead.</p>
<p>If the sum of the resulting values for <code>len</code> and <code>pos</code> exceed
<code>this.<a href="#length">length</a></
