CodeIgniter4 - Event pass by ???

Started to test a few things in CI4 and was wondering what the best way to handle modifying the input to a Event.
Seems to me perhaps just passing the values by reference might solve the problem?

PHP Code:

public static function trigger($eventName,&...$arguments): bool { 


For example if I have:

PHP Code:

$a = 'this is something a trigger needs to modify maybe (let the trigger figure it out)';

$boolean = events::trigger('modify_text',$a); 


What would be the best way to modify the $a text value? What if I have multiple modify_text triggers with multiple priority levels? Shouldn't everyone in "priority" be able to take a shot at it? maybe 1 trigger adds <p> if it contains "this" as the first word and then later down the event "list" it adds <b> if it doesn't already start with a html element. 

Like I wrote about prefixing the trigger functions ...$arguments with & should do the trick???

I look forward to your input.
