Inheritance

In short, I’ve been using F# for several years now and didn’t realize that F# record types can’t be inherited. I think this demonstrates that inheritance for data types is unnecessary when actions and data are separated, and it may hint at a larger trend in programming languages.

I fooled myself for a moment into thinking F# has ad-hoc polymorphism. Interface inheritance in F# looks a lot like traits in rust. So, why doesn’t F# support trait-like polymorphism.
