The call to the method kint\KintBootup::initFunctions() seems un-needed as the method has no side-effects.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
PHP Analyzer performs a side-effects analysis of your code. A side-effect is
basically anything that might be visible after the scope of the method is left.


Let’s take a look at an example:


class User
{
    private $email;

    public function getEmail()
    {
        return $this->email;
    }

    public function setEmail($email)
    {
        $this->email = $email;
    }
}





If we look at the getEmail() method, we can see that it has no side-effect.
Whether you call this method or not, no future calls to other methods are affected
by this. As such code as the following is useless:


$user = new User();
$user->getEmail(); // This line could safely be removed as it has no effect.





On the hand, if we look at the setEmail(), this method _has_ side-effects.
In the following case, we could not remove the method call:


$user = new User();
$user->setEmail('email@domain'); // This line has a side-effect (it changes an
                                 // instance variable).
