Hey all, I figured it was time to move to a "modern" language and I thought 
I'd give go a try. So far, I'm really enjoying it. I'm just getting started 
and I had a question about parentheses. Though, I guess it's really about 
how go parses lines of code and what counts as a delimiter.

Anyway, in the get started section on error handling 
<https://go.dev/doc/tutorial/handle-errors>, why are parentheses required 
around string and error here:

func Hello(name string) (string, error) {...

but not around message and nil here:

return message, nil

I tried searching a bit but I couldn't come up with anything about such a 
basic topic.

Thanks!
