I registered an object an I'm trying to get the following below:

 stdClass Object (
         [test] => test
         [users] => stdClass Object (
                 [createSave_email_subject] => - New
 User Account
                 [createSave_email_pass] => The user
 was created, and an email was sent to
 them!
         ) )

Smarty Kodu:

 Works: 
{language->test}   

Doesn't Work:
{language->users->createSave_email_subject}
{language[users]->createSave_email_subject}
{language.users->createSave_email_subject}
{language->users.createSave_email_subject}
{language->users[createSave_email_subject]}
