21 * Smarty 3 does implement two different syntax's:
22 * - {for $var in $array}
23 * For looping over arrays or iterators
24 * - {for $x=0; $x<$y; $x++}
26 * The parser is generating different sets of attribute by which this compiler can
27 * determine which syntax is used.
29 * @param array $args array with attributes from parser
30 * @param object $compiler compiler object
31 * @param array $parameter array with compilation parameter
