>What does happen when you have parent's with the same properties and methods and they conflict?

The programmer must explicitly impiment the conflicting member function (C++ talk for method), this can be as simple as using the scope resolution operator to call the appropriate parent's member function.

It is not worth the trouble. Multiple inheritance is too tedious to simulate, the language must support it directly for it to be easy to use. Look at the way FoxPro handles data, contrast this with handling data in other languages.
