You soon get used to the pattern:

  blah, err := foo(...)
    if err != nil {
      return nil, err
  }

and it's sister:

  blah, err := foo(wibble)
    if err != nil {
      return nil, errors.New("foo error with blah due to: " + wibble)
  }

After a while I got to like passing errors carefully back up the call stack , cleaning them up, rewriting them and making them more useful.

My Go programs have far better (more detailed & relevant) error messages than any of my other code.
