You are talking about expression problem: https://en.wikipedia.org/wiki/Expression_problem

"Extend program with new data types and new functions"

It is quite well studied and solved in various languages. And, in my opinion, typical OO language solution does not come as especially succinct.

I wouldn't say the expression problem is "solved"; various languages pick different tradeoffs, but the underlying problem is still there.

The best description I've seen of this is at https://www.tedinski.com/2018/02/27/the-expression-problem.h...
