The original creator of the C++ STL has said in interviews that after a long career of C++ development, he still never uses -- and sees no use for -- any model of inheritance for anything. I've since learned that my own C++ code is much better when I very sparingly, or never, subclass anything. This has the added benefit of also never using vtables.
