      <p>Returns a lazy iterable of the leading elements satisfying <code>test</code>.</p>
<p>The filtering happens lazily. Every new iterator of the returned
iterable starts iterating over the elements of <code>this</code>.</p>
<p>The elements can be computed by stepping through <a href="dart-collection/ListQueue/iterator.html">iterator</a> until an
element is found where <code>test(element)</code> is false. At that point,
the returned iterable stops (its <code>moveNext()</code> returns false).</p
