Coroutines are popular!
Python: PEP 0492 (accepted on May 5, 2015)
async def abinary(n):
if n <= 0:
return 1
l = await abinary(n - 1)
r = await abinary(n - 1)
return l + 1 + r
HACK (programming language)
async function gen1(): Awaitable<int> {
$x = await Batcher::fetch(1);
$y = await Batcher::fetch(2);
return $x + $y;
}
DART 1.9
Future<int> getPage(t) async {
var c = new http.Client();
try {
var r = await c.get('http://url/search?q=$t');
print(r);
return r.length();
} finally {
await c.close();
}
}
C#
async Task<string> WaitAsynchronouslyAsync()
{
await Task.Delay(10000);
return "Finished";
}
C++17
future<string> WaitAsynchronouslyAsync()
{
await sleep_for(10ms);
return "Finished“s;
}
