TYPO3 Core

In sysext "form" many methods are implemented twice.
Many methods just call his parents without any modification.

One example is tx_form_System_Validate_Digit::__construct():

/**
 * Constructor
 *
 * @param array $arguments Typoscript configuration
 * @return void
 */
public function __construct($arguments) {
    parent::__construct($arguments);
}

This is quite useless, because due OOP, the parent method is called, if the local class does not provide a local / override method.
