+<p><a href="https://twitter.com/TheDonRaab">Donald Raab</a> posted an article about set operators using Java collections and <a href="https://github.com/eclipse/eclipse-collections">Eclipse Collections</a>. That post focuses
+on the <em>union</em>, <em>intersection</em> and <em>difference</em> operators. We’ll add in
+<em>symmetric difference</em> since Groovy supports operator overloading for that
+operator also.</p>
+</div>
+<div class="paragraph">
+<p>First, a quick refresh about the operators for two sets <strong>A</strong> and <strong>B</strong>:</p>
+</div>
+<div class="paragraph">
+<p><span class="image"><img src="img/SetOperators.png" alt="SetOperators"></span></p>
+</div>
+<div class="paragraph">
+<p>We’ll use the same emoji sets from Donald’s post:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">Set OCT = ["🍁", "🍃", "🎃", "🥧", "🍫", "🌝", "👻", "🌽", "🍎", "🪵", "☕️"]
+Set NOV = ["🍂", "🍁", "🥧", "🦃", "🌽", "🍎", "🪵", "☕️"]
+Set DEC = ["🥧", "🦃", "⛄️", "🍎", "🌰", "🛷", "🪵", "🎄", "☕️"]</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Groovy lets you write the same code as in Donald’s post but also offers
+operator overloading for these operators as follows:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">assert (OCT & NOV & DEC) == ["🪵", "🥧", "🍎", "☕️"] as Set
+
+assert (OCT | NOV | DEC) == ["🪵", "🦃", "🌰", "🛷", "🍎", "🎄",
+ "🍫", "🌝", "☕️", "🥧", "⛄️", "🍁",
+ "🍂", "🍃", "👻", "🌽", "🎃"] as Set
+
+assert (OCT - NOV - DEC) == ["🍫", "🌝", "🍃", "👻", "🎃"] as Set
+assert (NOV - OCT - DEC) == ["🍂"] as Set
+assert (DEC - OCT - NOV) == ["🎄", "🌰", "⛄️", "🛷"] as Set
+
+assert (OCT ^ NOV ^ DEC) == ['⛄️', '🌰', '🛷', '🎄', '🍃', '🎃', '🍫', '🌝',
+ '👻', '🍂', '🥧', '🍎', '🪵', '☕️'] as Set
+assert (NOV ^ OCT ^ DEC) == ['🍂', '🍃', '🎃', '🍫', '🌝', '👻', '🥧', '⛄️',
+ '🍎', '🌰', '🛷', '🪵', '🎄', '☕️'] as Set</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Since operator overloading is extensible in Groovy, you can have similar
+shorthand notation for your domain objects also. Enjoy!</p>
