This looks like a very complicated way of solving something for which there is already a solution: channels and contexts. Here's the pattern I often use: https://go.dev/play/p/mrQFLAc11QU https://go.dev/play/p/mrQFLAc11QU It should be doable to express this somewhat simpler using a (genericized) helper function to take out some of the work of writing the ListItems function. Since there is already a way to do this I don't think the language should be cluttered with more ways to essentially do the same thing. It is better to push people to develop a vocabulary of idioms that uses fewer features rather than introduce "more stuff".
