You may aus well ask "How do interfaces in OO programming deal with this?".
It's a good question. And the answer is, the top level function does not list every interface used by the call tree. Nested function calls test at runtime if a particular interface is supported by an object, using dynamic casting or QueryInterface() calls. It's fundamentally different from traits and concepts.
