So wait, go has handle errors by returning them, but it also doesn't force you to actually handle all return values? I thought that was the entire point of impl

  You're sort of forced to handle them, in that if a function returns (Data, error), you need to assign the error to a variable (or do data, _ := func(), but at least that indicates you're intentionally ignoring the error), and since Go treats unused variables as a compile failure, you might as well check them properly. But there's nothing that says you must check them, no.

    Ah thanks, that's kind of what I thought. I've read examples of Go but haven't written a line of it myself. the way GP described it made it sound like foo, err = bar() was merely a convention and you could do foo = bar() and drop err. If you have to add ", _" that's fine.
