It's a generic function with compile-time compatibility checks.
What does this have to do with inheritance? This is just a generic function.

This doesn't sound any different from how people usually talk about inheritance.
I am not convinced it gives you anything more than composition does. Composition is very easy to setup and easy to change. And there are certainly functional ways to do runtime polymorphism.
