That test can fail. See code below:

<?php
class anon_test {
	public function __invoke($args) {
		
	}
}

$anon_test = new anon_test();
var_dump(is_callable($anon_test) && is_object($anon_test)); // bool(true)

var_dump($anon_test instanceof Closure); // bool(false)
?>

It seems that the only way to truly know if a variable contains an anonymous function is to use the "implementation detail" that we are warned not to rely on.

Cheers
