The difference is in how easy it is to detect the cause of problems. Mistakes like wrong function names are mostly easy to find and fix. Mistakes when using core.async can be very hard to track down.

Not at all my experience. Do you have any examples?

OP called it "clojure.async." I question how much they've really used it.

Enough to keep wondering if this is the case <! or <<! and if whether I'd be better off with a dead-stupid, surprise-free thread pool.
