+<p>The GPars implementation is less verbose compared to the Pekko implementation but Pekko

+</div>
+<div class="paragraph">
+<p>GPars supports a mixture of styles, some offering less verbosity at the expense of capturing some
+errors at runtime rather than compile-time. Such code can be useful when wanting very succinct code
+using Groovy’s dynamic nature. When using Groovy’s static nature or Java, you might consider using

+ else terminate()
+ }
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>The <code>StaticDispatchActor</code> dispatches the message solely based on the compile-time information.
+This can be more efficient when dispatching based on message run-time type is not necessary.</p>

+<p>We could also provide an alternative definition for <code>Greet</code> as follows:</p>
