That is a limitation of Javascript not core.async. Since you cannot block in Javascript (only one thread) you have to take the "callback"/async route for everything.
Emulating blocking by running a loop is a bad idea since you cannot even pause/sleep and while that loop is running nothing else can run, resulting in a hanging browser for example. Don't see why you'd need alt!! though, the (go ...) block should not hurt in any way. In Java it may not be the best option since the current thread might die but you don't have to worry about that in CLJS.
