Description:
------------
Since Traits can't be instantiated, it is impossible to get its methods.

Test script:
---------------
trait foo {
	protected $bar;
	
	public function set_bar ($bar) {
		$this->bar = $bar;
	}
}

$reflection = new ReflectionClass ("foo");

print_r ($reflection->getMethods ()[0]->getClosure ());

Expected result:
----------------
Closure Object
(
    [this] => EMPTY (WILD GUESS)

    [parameter] => Array
        (
             [$bar] => <required>
        )

)

Actual result:
--------------
PHP Warning:  ReflectionMethod::getClosure() expects exactly 1 parameter, 0 given

Hi, it's unclear what you're trying to do. You say that you're trying to get the methods of a trait through reflection - but your code is actually trying to create a closure, that could be called.

That is not possible.....traits are only callable once they've been included in a class. It would be a bit like trying to get a closure of an interface....until it's included inside a class it just isn't a real thing that can be called.

Calling getMethods on the reflection for the trait does return all the information about a traits methods. If you mean something else by "get its methods" please can you clarify.
