Puppet users - Feb 2014 - Combining stages with hiera

I have some Windows systems that I need to configure a user's profile. The 
user has to be logged into for the profile to be created. I came up with 
the solution below but it seems kinda hacky. I assume there is a better way 
to get the same effect without having a class inside a class? Is there a 
way to set a stage on a class when using hiera? 

I am using Windows 7 x64, Puppet Open Source 3.4.2, and Hiera 1.3.1

autologon.pp manifest

class autologon ($username, $password) {
    stage { 'user-creation':
        before => Stage['main'],
    }
    class {'autologon-internal':
        stage => user-creation,
        username => $username,
        password => $password,
    }
    reboot { 'user-creation':
        subscribe => Stage['user-creation']
    }
    
    class autologon-internal ($username, $password) {
        user { $username:
            ensure => present,
            groups => 'Users',
            membership => inclusive,
            password => $password,
        }
        registry_value { "HKLM\\software\\microsoft\\windows 
nt\\currentversion\\winlogon\\defaultusername":
            ensure => present,
            type   => string,
            data   => $username,
        }
        registry_value { "HKLM\\software\\microsoft\\windows 
nt\\currentversion\\winlogon\\defaultdomainname":
            ensure => present,
            type   => string,
            data   => $hostname,
        }
        registry_value { "HKLM\\software\\microsoft\\windows 
nt\\currentversion\\winlogon\\defaultpassword":
            ensure => present,
            type   => string,
            data   => $password,
        }
        registry_value { "HKLM\\software\\microsoft\\windows 
nt\\currentversion\\winlogon\\autoadminlogon":
            ensure => present,
            type   => string,
            data   => '1',
        }
    }
}

hiera yaml file
