              NULL Next              Str       ----> "Fred"       <--/
                                     Ptr Type  NULL      
                                     Ptr       NULL
                         
    

    The above diagram describes:

    {
        Name = "Fred"
    }



    NOTE - Looking at the above structures a few things
           Seem odd.
        
           Why is the Type field of the value 'Fred'
           T_IDENTIFIER

           Should we use T_STRING instead
