I'm not an expert in Go, and my experience is somewhat limited, however, a few years back I fixed a really subtle bug in a project that was related to the fact that errors _weren't_ being handled correctly. As a relative newbie to Go, the code in the diff[0] didn't appear to be doing anything wrong, until I added some print statements and realized that the numbers were not adding up correctly. IMO, if the returned value had been more like a Rust optional or result type, I think this issue would have either not been a bug in the first place, or it would have been easier to spot the bug.

EDIT: The fact that this was a bug at all makes me fear for the rest of the code base. If this one slipped through the cracks, how can I know that the rest of the code base is correct?
