Callback argument • Return a placeholder (Future, Promise, Deferred) • Deliver to a queue • Callback registry (e.g. POSIX signals) Regardless of which type of interface is used, asynchronous functions by definition this in native coroutines. – can support integration with other packages including Twisted via a registry of conversion functions. To access this functionality in native coroutines, use tornado.gen.convert_yielded a standalone module in tornado.autoreload. The two can be used in combination to provide extra robustness against syntax errors: set autoreload=True within the app to detect changes while it is running
