Clojurians Log v2

Depending on your perspective, core.async is a form of structured concurrency. But in the more pedantic definition, where basically you have a tree of concurrent dependencies, you can use https://github.com/leonoel/missionary It doesn't use core.async, but it uses the same internal approach as core.async to enable lightweight threads.

Thanks @didibus ! Going with some helpers over core-async for now.

And it's the best implementation of a form of structured concurrency I've seen in Clojure.

Loom in newer JDKs also have I think experimental structured concurrency, I think that can be used from Clojure as well.
