I'm not familiar with Go and I'm confused by the fact that even though the returned variable is named, e.g. "ch", that name is never mentioned in the function b

  Naked returns. Basically, you just write "return" and that returns the values declared as named return parameters. If they are never mentioned in the body you probably have a return of the default nil value for the named return variables. But then at least one return is not naked and returns some value, discarding the named one. I think it's a bad use of named returns.

  Nothing. The named return value is default-initialised (zero-initialised) before the function body (you don't have to assign to it, you can just modify it in place), and if you don't explicitly return a different value it will be returned regardless of you using it or not.
