hi o/ I get it that async/<!! doesn't exist in cljs because we're technically running a single thread, but what's a good replacement for a REPL use case when I just want to read a single thing from a channel? (something like await read(chan) in the web inspector's console, basically). I can run poll! a few times, but when my api is async and returns a new chan on every call it becomes a bit inconvenient to use.
