https://ask.clojure.org/index.php/tag/multimethod https://ask.clojure.org/index.php/15187/implement-async-cljs-for-protocol-functions-multi-methods <p>In ClojureScript (as of <code>1.12.145</code>) one can declare a function (<code>defn</code>, <code>fn</code>) to be async by adding the metadata <code>^:async</code>. However, the same is not applicable to protocol functions and multi-methods. Since async is an invocation semantic, should it be carried over to protocol functions and multimethods? (If yes, should it apply to the protocol definition in <code>defprotocol</code> or to the protocol implementation in <code>reify</code>?)</p> <p>If async is not to be allowed in protocol functions and multimethods, then the documentation should clearly mention the omissions, alternatives and workaround.</p> ClojureScript https://ask.clojure.org/index.php/15187/implement-async-cljs-for-protocol-functions-multi-methods Sun, 19 Jul 2026 11:53:45 +0000
