However, that conflicts with how typehints work currently in PHP:
public function setContainer(Container $container = null)
{
$this->container = $container;
}
This is perfectly valid currently, and allows "unsetting" a value
easily. I'd expect scalar hints to work exactly the same way -- in other
words, null, or a value that satisfies the hint.
