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. |
