 +By the way, current realization simply add "_ _construct" method into class via AST injection. 
 +Another words, code "($cc, $whells)" considered  as zend_ast node "parameter_list" and accordingly processed by standart way. You can declare property type like you declare them inside standard method. Also you can declare defaults for parameters, use "..." notation (there is a nuance) and do everything else.

 +===== Restrictions =====
 +This syntax can't be used with anonymous classes because those classes instantiated at once they declared and same syntax is used for forwarding parameters directly into constructor.
