Great! So while this works, you'll still have a few problems, namely in
places that are not in a tail call position.
For example, core.async support this sort of behavior
;; inside an argument list (not a let)
(go
(println "GOT Value" (<! c)))
;; in a do
(go
(do (println "Before")
(<! c)
(println "After")))
;; Before a branch
(go
(if (<! c)
(println "true")
(println "false")))
In essence what you have is a bit of syntactic sugar over callbacks. It's
still "callback hell" in the sense that you have to always be in a tail
recursive position, and have to manually transform your code into
continuation passing style.
