Yeah, though that’s also kind of my point. You know and I know (having learned the hard way) that the mechanism involves storing parameters and intermediate values in an object that is referred to later. It’s obvious now I know, but the design hides that from the user - they aren’t supposed to care about that. However, the footguns are still present. There should have been language features to prevent temporaries binding to const& for coroutines, but (according to a friend) the language doesn’t distinguish coroutines and subroutines at that level (… or something?)

Same problem with ranges. The footguns are remnants of abstracting something complex with a friendly interface and failing to secure it. It’s great for people who know the implementation, and it’s obvious where memory issues appear - but if you don’t know the implementation then you end up with holes in your feet.
