Since the boat has already sailed for Golang having async/await from the start, adding it now would require maintaining compatibility with uncolored functions.

Since the boat has already sailed for Golang having async/await from the start, adding it now would require maintaining compatibility with uncolored functions. Waiting for a channel to have data from a go func is similar. JS has similar compatibility with uncolored code using Promises. Python's migration to async/await is a lot worse because it didn't have coherent parallelism features to begin with. Exceptions are a smaller deal than async/await. Basically instead of manually writing "if err" everywhere, it's implicit if you aren't catching it. The most popular languages do this. Rust "?" syntax is also a decent compromise.
