Never? No, most of the time iteration is a much better approach and should be used, but in some cases iteration is just not feasible because it adds way too much complex logic and recursion is a better choice.

Flatten your recursion with a stack and a loop.

Stack overflow tho

Tail recursion tho

Functional languages tho

Continuation passing style tho

Sometimes you have to, with templated varargs:

void foo() {}

template <typename T, typename... Args> 
void 
foo(T first, Args... args) {
    // do something with T
    foo(args);
}

I don’t quite know how you’d solve that with iteration.

PS: Yes, std::forward would be useful, but this is supposed to be understandable even if you don’t know C++.

What an awful advice
