`syntax.async_await`

Code marked async or await.

Area 3, Logic; not declinable; the next step is usually the agent's.

A call gives its result when it returns, so nothing is marked async or await.

example

type Count = Int {    min: 0}function same(count: Count) -> Count {    return count}function same_twice(count: Count) -> Count {    return await same(count)}

jadpo checkcheck failed: 1 error, 1 file

error Jadpo has no await

--> main.jadpo:10:12

   |10 |     return await same(count)   |            ^^^^^ remove `await`

reason: async and await mark code that waits for a result in JavaScript, TypeScript, Python, Rust, C# and Swift; a Jadpo call always gives its result when it returns, so there is nothing to mark.
next: Remove await (agent)
