+# Control structure - `Use`
+
+While working with inside a template, it might be needed that you reference some other namespaces.
+
+The use clause works exaclty like PHP's vanilla top of the page `use`.
+
+**[PICEA]** So, using this code:
+
+```html
+{% use AnyVendor\My\Super\Randomizer %}
+
+{# One chance out of ten to end this loop %}
+{% while Randomizer::run(1, 10) === 10 %}
+    {% if Randomizer::run(1, 100) < 50 %} 
+        <span>Lower than 50 !</span>
+    {% else %}
+        <strong>Greater than 50 !</strong>
+    {% endif %}
+{% endwhile %}
+
+<h4>DONE !</h4>
+```
+
+**[HTML]** Could render as such output:
+
+```html
+<span>Lower than 50 !</span>
+<span>Greater than 50 !</span>
+<span>Lower than 50 !</span>
+<span>Greater than 50 !</span>
+<span>Lower than 50 !</span>
+<span>Lower than 50 !</span>
+<h4>DONE !</h4>
+```
