Sorry, I don't understand what you're saying. Are you saying that because there's a proposal in v2 for error values to not be 1st class values, therefore they're not in v1?
I think it’s that in Go multiple return values aren’t a first class value. It’s just two separate values. Whereas in Rust or Haskell they’d be a single, first-class Result<a> (or whatever) value.
