Agreed. As a concept they're all the same thing.

Another way of phrasing my query is that given these are all basically ML-style constructs, why would the examples not be ML? And I was assuming the answer to that is "the sorts of people reading these blogs in 2024 are more familiar with Rust"

I think a second reason might be that translating OCaml/Haskell concepts to Python has that academic connotation to it. Rust also (thanks to PyO3) has more affinity to Python than the ML languages. I guess it isn't a surprise that this post has Python, C++, and Rust, all "commonly" used for Python libraries.
