Alternatively, until futures are a thing, you can call `beginAsync` twice to
start to async tasks:
func process() -> Void {
beginAsync {
let dataResource = await loadWebResource("bigData.txt")
//....
}
print("BigData Scheduled to load")
beginAsync {
let dataResource = await loadWebResource("smallData.txt")
//....
}
}
Futures have a number of advantages. For instance, you can use a nullable
Future to keep track of whether the task has been started at all.
