I just want to point out that just because go lacks a good way of handling error conditions, doesn't mean exceptions are the best way. Haskell has exceptions, and I wish it didn't. Because it has better options for dealing with error conditions, like Maybe and Either. If you are checking for an error condition every ten lines, those are by far nicer than using exceptions.
