+<p>It may not be the most efficient implementation of this functionality,
+but it has a nice symmetry. Let&#8217;s now explore some stream-based solutions.</p>
+</div>
+<div class="paragraph">
+<p>We can start off with a <code>tails</code> gatherer:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">&lt;T&gt; Gatherer&lt;T, ?, List&lt;T&gt;&gt; tails() {

+    )
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>In the integrator, we just store away all the elements,
+and in the finisher we do all the work. This works but isn&#8217;t really
+properly leveraging the stream pipeline nature.</p>
+</div>
+<div class="paragraph">
+<p>We can check it works as follows:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">assert search.stream().gather(tails()).toList() ==
+    [['brown', 'fox'], ['fox'], []]</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>We could continue with this approach to create an <code>initsOfTails</code> gatherer:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">&lt;T&gt; Gatherer&lt;T, ?, List&lt;T&gt;&gt; initsOfTails() {
+    Gatherer.ofSequential(

+            state.tails()*.inits().sum().each(downstream::push)
+        }
+    )
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Again, all the work is in the finisher, and we haven&#8217;t really made use

+</div>
+<div class="paragraph">
+<p>It still works of course:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">assert words.stream().gather(initsOfTails()).anyMatch { it == search }</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>But it might have been more efficient to have collected
+the stream as a list and used Groovy&#8217;s built-in <code>inits</code> and <code>tails</code> on that.</p>
+</div>
+<div class="paragraph">
+<p>But all is not lost. If we were willing to tweak the algorithm slightly,
+we could make better use of the stream pipeline. For example, if we don&#8217;t
+mind getting the <code>inits</code> results in the reverse order, we could define the following
+gatherer for <code>inits</code>:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">&lt;T&gt; Gatherer&lt;T, ?, List&lt;T&gt;&gt; inits() {
+    Gatherer.ofSequential(
+        () -&gt; [],
+        Gatherer.Integrator.ofGreedy { state, element, downstream -&gt;
+            downstream.push(List.copyOf(state))
+            state &lt;&lt; element
+            return true

+            downstream.push(state)
+        }
+    )
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">

 <h2 id="_conclusion">Conclusion</h2>
 <div class="sectionbody">
 <div class="paragraph">
-<p>We have had a quick glimpse at using gatherers with Groovy.
-We are still in the early days of gatherers being available,
+<p>It is great that Groovy has a rich set of methods that
+work with collections. Some of these methods have stream
+equivalents, and now we see that using gatherers with Groovy,
+we can emulate more of the methods.
+Not all algorithms need or benefit from using streams,
+but it&#8217;s great to know that with gatherers, we can
+likely pick whichever style makes sense.</p>
+</div>
+<div class="paragraph">
+<p>We are still in the early days of gatherers being available,
 so expect much more to emerge as this feature becomes more mainstream.
 We look forward to it advancing past preview status.</p>
