I wrote the paper that this article is describing [1], and can answer questions. The paper is probably more approachable than you think. Basically I rewrite code like `let intermediate_value = recursive_call(...)` into code like `output += recursive_call(...)`, which allows you to make recursive calls in a way that avoids ever storing the intermediate value. That's important in contexts where you can't simply discard information, namely quantum computing. [1]: https://arxiv.org/abs/1904.07356
