Recursion that cannot support arbitrary recursion depths is not optional, but broken. Going from a high-level programming language to assembly is going down the level of abstraction. I don't recommend that, unless there is a really good reason to. Iteration and tail recursion is the same level of abstraction. I am not arguing against recursion. I am saying, do it right. Otherwise it is useless.
