I suspect the point was not that add can be described as doing single dispatch (it can't), but rather that add could possibly be implemented in terms of lower-level functions doing single dispatch. If that was the point, perhaps the next level point is trying to be that single dispatch is a sufficient mechanism that can be augmented (as above) to handle more complex cases.

This is true, but as it is of everything Turing-complete. Generic functions don't add anything that you can't already do manually (for example with custom registries) :-)

Regardless, I also agree that single-dispatch is much easier to reason about, and good enough for now.

Regards

Antoine.
