Laravel bind vs singleton

Container::singleton is the same as Container::bind with the third parameter set to true. 1

class MyClass
{
    public $value;
}


public function test_bind()
{
    $container = new Container();

    $container->bind(MyClass::class);

    $instance1 = $container->make(MyClass::class);
    $instance2 = $container->make(MyClass::class);

    static::assertNotSame($instance1, $instance2);
}

public function test_singleton()
{
    $container = new Container();

    $container->singleton(MyClass::class);

    $instance1 = $container->make(MyClass::class);
    $instance2 = $container->make(MyClass::class);

    static::assertSame($instance1, $instance2);
}
