Go does not do that implicitly, there is an explicit "go" syntax. Gevent in Python does something similar [implicit switching] using a dirty monkeypatching. It is great while it works. Sooner or later the explicit cooperative concurrency such as provided by async/await syntax wins (e.g., asyncio, trio, curio Python libraries)
