 Smarty 3.1.30
 
-    Loop optimization {foreach} and {section}
-    =========================================
-    Smarty does optimize the {foreach} and {section} loops by removing code for not needed loop
-    properties.
-    The compiler collects needed properties by scanning the current template for $item@property,
-    $smarty.foreach.name.property and $smarty.section.name.property.
-    The compiler does not know if additional properties will be needed outside the current template scope.
-    Additional properties can be generated by adding them with the property attribute.
-
-    Example:
-        index.tpl
-        {foreach $from as $item properties=[iteration, index]}
-            {include 'sub.tpl'}
-            {$item.total}
-        {/foreach}
-
-        sub.tpl
-        {$item.index} {$item.iteration} {$item.total}
-
-    In above example code for the 'total' property is automatically generated as $item.total is used in
-    index.tpl. Code for 'iteration' and 'index' must be added with properties=[iteration, index].
-
     New tag {make_nocache}
     ======================
     Syntax: {make_nocache $foo}
