-      Not using the <literal>&amp;</literal> operator causes a copy of
-      the object to be made. If you use <literal>$this</literal> in
-      the class it will operate on the current instance of the
-      class. The assignment without
-      <literal>&amp;</literal> will copy the instance (i.e. the object) and
-      <literal>$this</literal> will operate on the copy, which is not
-      always what is desired. Usually you want to have a single
-      instance to work with, due to performance and memory consumption
-      issues.
