PHP namespaces do not resolve upwards

README.md

This is the same as trying to reference stuff in the global namespace, such as PHPs predefined functions. We shouldn't have to prefix them with "", they should just resolve anyway.

animal.php

<?php

namespace MyProject;

class Animal {

    public $sound = false;

    public function speak() {
        echo $this->sound;
    }
}

dog.php

<?php

namespace MyProject\Animal;

class Dog extends Animal {
    public $sound = 'whoof';
}

result.txt

Fatal error: Class 'MyProject\Animal\Animal' not found in /Users/Nathaniel/Projects/test/animal/dog.php on line 5

run.php

<?php

namespace MyProject;

require 'animal.php';
require 'animal/dog.php';

$dog = new Animal\Dog;
$dog->speak();
