Avoid multiple inheritance

If you have an example of multiple inheritance in your design, assume you have made a mistake and prove otherwise. -- Riel's Heuristic 6.1, Arthur Riel 1996

Explanation

Riel believes that multiple inheritance (MI) is not evil or undesirable; however, it is rarely used correctly. If a situation exists that you believe requires multiple inheritance you should consider this carefully.
