For the love of god don't do this!

gistfile1.aw

<?php

foreach ($this->models as $model) {
     $_file = '../' . $this->app . 'Models/' . $model . 'Model.php';
     $_class = $model . 'Model';

    if (file_exists($_file)) {
        require_once $_file;
        $this->{ucfirst($model)} = new $_class(null, dbConfig::$default);
    } else {
        $class = 'class ' . $_class . ' extends Model { }';
        eval($class);
        $this->{ucfirst($model)} = new $_class(null, dbConfig::$default);
    }
}

You know that instead of creating a new gist when you want to change something, you can just edit the one you have? The gist will be versioned.
