Useful when dealing with API's that expect data in one type but the code base is using another.
For example, using an API that expects a 3d vector as one type whilst using a different type throughout the rest of the code base.
My example inherits and adds user defined type conversion to the derived class. This is because I wanted to keep using the parent type in the code and add conversion to and from another type.
This Stack Overflow answer uses a templated wrapper to support conversion.
