     * If you would like your shell interaction to affect the state of the
     * current context, you can extract() the values returned from this call:

     *     foreach ($items as $item) {

     *         var_dump($item); // will be whatever you set $item to in Psy Shell
     *     }
     *
     * Optionally, supply an object as the `$bindTo` parameter. This determines
     * the value `$this` will have in the shell, and sets up class scope so that
     * private and protected members are accessible:
     *
     *     class Foo {

     * For the static equivalent, pass a class name as the `$bindTo` parameter.
     * This makes `self` work in the shell, and sets up static scope so that
     * private and protected static members are accessible:
     *
     *     class Foo {
     *         static function bar() {
     *             \Psy\debug(get_defined_vars(), get_called_class());
