I don't know if you mean something deeper, but core.async has <!, >!, and alts! variants that don't require a go block: <!!, >!!, and alts!!. You can just use them like a function. But they block the thread. So if you e.g. naively call it in the REPL you will block it indefinitely. E.g.: (>!! (chan) "this will block the REPL") The idea would be to pass a channel to multiple virtual threads which use the blocking versions.
