This is used to assign values to the templates by reference.
If you assign a variable by reference then change its
value, the assigned value sees the change as well. For
<a class="link" href="advanced.features.html#advanced.features.objects" title="Objects">objects</a>,
<code class="varname">assign_by_ref()</code> also avoids an in-memory copy of the
assigned object.
See the PHP manual on variable referencing for an in-depth
explanation.
