I think I get coroutines in theory. It's the C++ specific complexity that is the hardest barrier. Thanks for the explanation though

Yes, a lot of extra junk is needed to make them actually work, but the extra junk goes a long way toward obscuring what you actually need to know.

Ultimately, though, you are right that you have to understand it all, once, even if you can't remember it all a month later. The explanations I find online are not good at presenting just the details you need when you need them, and building up to the full picture.
