* For looping over arrays or iterators
*
* - {for $x=0; $x<$y; $x++}
* For general loops
*
* The parser is gereration different sets of attribute by which this compiler can
* determin which syntax is used.
*
* @param array $args array with attributes from parser
* @param object $compiler compiler object
* @return string compiled code
