100% agree. That's why eventually I want to learn F# (currently my main driver is C#). It features more advanced type system and I love static typing, because by itself it provides nice guarantees. F# brings it further by guaranteeing specific state. I may learn F#, but I don't think I'm gonna use it in existing code base, as maintainability with fellow developers or whoever works after me is perhaps more important than F#... Not that your example cannot be achieved in C# - it can. But what I suspect F# just brings those static typing guarantees further https://fsharpforfunandprofit.com/posts/designing-for-correctness/ https://fsharpforfunandprofit.com/posts/designing-for-correc...
