Hyphotetical: Example of generating php code with latte

example.phpg

<?php
/**
 * {reusable}
 */
class GenericLogOnEventSubscriber implements Subscriber
{

	/**
	 * {args2prop [ private|public|protected]}
	 */
	function __construct(Logger $logger, $format);


	function getSubscribedEvents()
	{
		return [ /* {$event} */ => 'eventHandler' ];
	}


	function eventHandler()
	{
		$this->logger->log(spritfv($format, func_get_args()))
	}

}

It could be done by extracting comments and parsing them as templates. If rendered template is empty or only whitespaces removing comment else writing output. Some macros could just set flags etc.
