Improvements to Dispatcher class

[fadrian06]

Tired of declaring after filters with the first parameter without doing anything?

DELETE IT :D, nothing will be broken.

Dispatcher now supports after filters with the only useful parameter.

Flight::after('myMethod', function (&$params, &$output) {
  // $params Even if it is used it does not affect, but it had to be declared yes or yes even if it does nothing.
});

Now...

Flight::after('myMethod', function (&$output) {
  // goodbye useless $params 
});

IMPORTANT: both ways work exactly the same. Only one is shorter and cleaner.

To even make it even cleaner, you could change the filter to a PHP 7.4 arrow function.

Flight::after('myMethod', fn (&$output) => doMagic($output));

Just make sure that what you do in the arrow function doesn't return false, unless you want to make other after filters for the same mapped method not run.

@fadrian06 Why'd you close the PR? It's a good PR just needs a few tweaks
