I agreed with your parent post and upvoted you, but too many inexperienced with functional programming claim it is all (or too much) recursion. I think this should be challenged.

Yes recursion is a useful tool, just like GOTO and is sometimes necessary or more practical. But it is better to e.g. use a fold if you can because that further constrains and aids reasoning. For example, a fold will always terminate unlike general recursion.

I recommend looking into recursion schemes, if you aren't familiar with them.
