what is missing here?

public final class accounts
{
     public:
         static table_user user;
}

public final class table_user
{
     private:
         static uint32 dummy1;
         static string dummy2;
         static DateTime dummy3;
         static ubyte dummy4;
     public:
         static @property auto user_id_t() { return 
typeof(dummy1); }
         static @property auto name_t() { return typeof(dummy2); }
         static @property auto alias_t() { return typeof(dummy2);}
         static @property auto pers_email_t() { return 
typeof(dummy2); }
         static @property auto corp_email_t() { return 
typeof(dummy2); }
         static @property auto password_t() { return 
typeof(dummy2); }
         static @property auto last_login_t() { return 
typeof(dummy3); }
         static @property auto active_t() { return typeof(dummy4); 
}
         static @property auto id_lang_t() { return 
typeof(dummy4); }
         static @property auto function_t() { return 
typeof(dummy4); }
         static @property auto register_date_t() { return 
typeof(dummy3); }
}

for every property it throws me an error at compile time: type 
($) has no value.
I'm trying to do a wrap of a database so when getting a resultset 
using mysql-native I can do
result.front()[0].get!(accounts.user.user_it_t);
si it's more readable.
