IME, one of the hardest things getting programmers from other languages used to with Go is drilling in that "the 'default' thing to do with an error is to return it". `main()` is a notable exception to that rule of thumb. It's almost like code in main() is a different dialect than the rest of the codebase. Let's just make it uniform.

I feel like a lot of the griping that people have about Go error handling would go away if people internalized that rule of thumb, and this would make that easier.
