Many people misunderstand Composition, the Composition concept is very important and it has nothing to do directly with memory management. Software is a model of real-world object, composition is the concept of real world that we're modeling.

Software is not a model of real world objects. Software is a model of the *solution* to a problem. And it needs to be a model that takes into account the forces of being implemented in a computer. As one consequence, this model will look significantly different based on, for example, the language used to describe the implementation.
