How to access configs from autoloaded config files in a layout / view script in Zend Framework 2?

Question

I would like / have to manage some settings in ZF1 style and provide the view with the infomation about the current environment.

/config/application.config.php

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

/config/autoload/env.local.php

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

In a common view script I can do it over the controller, since the controllers have access to the Service Manager and so to all configs I need:

class MyController extends AbstractActionController {

    public function myAction() {
        return new ViewModel(array(
            'currentEnvironment' => $this->getServiceLocator()->get('Config')['environment'],
        ));
    }

}

Is it also possible to get the configs in a common view directly?

How can I access the configs in a layout view script (/module/Application/view/layout/layout.phtml)?

(My implementation/interpretation of) Crisp's suggestion:

Config view helper

<?php
namespace MyNamespace\View\Helper;

use Zend\View\Helper\AbstractHelper;
use Zend\View\HelperPluginManager as ServiceManager;

class Config extends AbstractHelper {

    protected $serviceManager;

    public function __construct(ServiceManager $serviceManager) {
        $this->serviceManager = $serviceManager;
    }

    public function __invoke() {
        $config = $this->serviceManager->getServiceLocator()->get('Config');
        return $config;
    }

}

Application Module class

public function getViewHelperConfig() {
    return array(
        'factories' => array(
            'config' => function($serviceManager) {
                $helper = new \MyNamespace\View\Helper\Config($serviceManager);
                return $helper;
            },
        )
    );
}

Layout view script

// do whatever you want with $this->config()['environment'], e.g.
<?php
if ($this->config()['environment'] == 'live') {
    echo $this->partial('partials/partial-foo.phtml');;
}
?>
