I can say for a fact I had no problems writing recursive algorithms back in the 90s when total ... example. And for recursive-only ... statement "Don't ever use recursion in production code".

Note: this is prototype code, just designed to demonstrate to myself that a thing is feasible. If you can follow my code, you can see how deep recursion is useful.
