asynccljmacro
(async expr)If expr is a fn or defn form, its body will
run asyncronously. Otherwise, expr will itself
run asyncronously, and return a CompletableFuture.
WARNING: all let blocks inside an async block
return CompletableFutures.
All async exectution occurs on the ci/*executor* pool,
which is bound to the common ForkJoinPool by default.
If `expr` is a `fn` or `defn` form, its body will run asyncronously. Otherwise, `expr` will itself run asyncronously, and return a `CompletableFuture`. WARNING: *all* `let` blocks inside an `async` block return `CompletableFuture`s. All async exectution occurs on the `ci/*executor*` pool, which is bound to the common ForkJoinPool by default.

(await v)Use inside async let blocks:
(async (let [x (async :x) y (await x)] y))
Will wait for the CompletableFuture to complete
before evaluation resumes.
Use inside `async` `let` blocks:
(async
(let [x (async :x)
y (await x)]
