Async Await - language feature

async doSomething => await somethingElse()

Example from C#:

public async Task<int> FindPageSize(Uri uri) 
{
    byte[] data = await new WebClient().DownloadDataTaskAsync(uri);
    return data.Length;
}

Example from bog:

let {print} = import "std.io"
let foo = fn()
    print("foo started")
    let bar_frame = async bar()
    print("in foo")
    let bar_res = await bar_frame
    print("foo finished")
    return bar_res
let bar = fn()
    print("bar started")
    suspend
    print("bar resumed")
    suspend
    print("bar finished")
    return 1
print("main started")
let foo_frame = async foo()
print("in main")
let res = await foo_frame
print("main finished:", res)
