I'm trying to override Eloquent's Query Builder.

I have tried the following for my `MyModel`:

```
<?php

class CustomQueryBuilder extends Illuminate\Database\Query\Builder
{
    public function get($columns = array('*'))
    {
        die('get');
    }
}

use CustomQueryBuilder as Builder;
class MyModel extends \Illuminate\Database\Eloquent\Model
{
    // the model that needs the custom query builder
}

```

But when I run `MyModel::get()` it still returns the object instead of dying.

Any ideas how to make this work?
