    19 # Checks : T classes inheriting from C classes.
       
    20 #
       
    21 # Reason : T classes that are derived from C classes may have a 
       
    22 # complex constructor and so need to be handled differently. 
       
    23 # It is better to make the T class into a C class, which will make 
       
    24 # the code easier to maintain.
