.env.php file(s) not working

Not sure if Laravel 4.2 has changed the way variables saved into $_ENV from the .env files or if it's my dev environment, but the variables in my "dot files" are copied to $_ENV in the format  $_ENV['stripe.api_key'] not $_ENV[ 'stripe']['api_key'].

Even though my .env.php file looks like this:
```
return array(
	'stripe' => array(
		'api_key' => 'sk_test_xxxxxx,
		'publishable_key' => 'pk_test_xxxxx'
	)
);
```

If I dd($_ENV); I can see them:
```
array (size=16)
  ...
  'stripe.api_key' => string 'sk_test_xxxxx' (length=32)
  'stripe.publishable_key' => string 'pk_test_xxxxx' (length=32)
```
