Timothy Baldridge provides an in-depth walkthrough of the compiler and state machine internals behind Clojure's core.async go macro.
The first part of a in-depth look into the internals of the Core.Async go macro. There's a lot to cover here, so forgive me if I go off on a few bunny trails along the way.

On “Help grokking core.async implementation of processing pipeline”
The videos would be these, and he shows some internals of a "parking" go-block here although you'll likely need a bit more of the video for context (he moves on to the execution strategy of core.async around here).

On “New Clojurists: Ask Anything”
As others have mentioned, core.async is a good example and there are even a series of Youtube videos about how the macro works: link to this video
It's actually a better example than many will admit to because not only does it show the strengths of macros, it also shows their limitations on how you can extend the language.

On “Compiling a functional language to Javascript”
They have an explicit loop/recur construct built in. Clojure's core.async is also compatible with ClojureScript. You might find the go macro internals relevant.

On “clojure.core.async: An unfulfilled promise”
No worries. This series will help improve your understanding of what goes on there, but won't do anything for tracing or debugging :)

Really, the best thing I found for trace/debug of core async it to test a blocking version then change it to non-blocking
