Invalid arity issue when wrapping a macro around twenty expressions

https://clojurians.slack.com/archives/C03QZH5PG6M/p1668017779830469

I have the following do! macro that wraps individual exprs in js/await. When I have greater than ~20 expressions in the body of the do!, the compiler throws an error

(defmacro do!
  [& exprs]
  `(do
     ~@(map (fn [expr#] `(js/await ~expr#)) exprs)))

;; usage
(do!
  (first-async-fn)
  ...
  (twentieth-async-fn))

I'm able to work around this issue by wrapping a subset of the expressions (to get under ~20) into their own functions and invoking them i.e.

(do!
  (^:async (fn []
    (do!
      (first-async-fn)
      ...
      (tenth-async-fn)))
  (^:async (fn []
      (eleventh-async-fn)
      ...
      (twentieth-async-fn)))))
