Clojure has some awesome libraries, but unless you can show some use cases where futures/promises and core.async make it possible (or even just easier) to implement functionality compared to async/await (or F# async) I'm not inclined to take your word for it.
In Clojure CSP is implemented as a library (core.async), no changes to the compiler needed. Now that's power.
(disclosure, I helped write core.async)
core.async looks very well-rounded, congratulations on a fine job.
Futures and promises aren't unique to Clojure. For example, AliceML had them ages ago.
After thinking it over, I'm going try implementing them for my ExtCore library for F# (https://github.com/jack-pappas/ExtCore). Thanks to the GP for the idea.
