In Eiffel we have multiple inheritance.
It's such a powerful tool.
And a natural way to model the world.
For example if you think of your typical OOP book
You have
Vehicles with engines
* cars that move on roads
* planes that move on air
* and boats that move on water.
But then comes an aqua-plane and it breaks your inheritance tree!
But with multiple inheritance is the most natural thing to have a plane that is also a boat and a car.
In Eiffel we favor the appropriate tool that better represents the world.
