If you start by at the base level, like if you want to switch to generator code, it's difficult because you have to put generators all the way down to the leaves of your call stacks. But if you start with generators at the leaves, then it's very easy to start saying, hey, I'm going to turn this into a streaming generator. So creating those cascades of generators becomes very straightforward. And so you can get quick, you know, very fast executing code that's easy to follow and uses a low amount of memory, very,you know, very cheaply.
