> Noticed while playing with a Flight client. This snippet inadvertently
> suppresses all errors that come from the underlying MessageReader since
> {{next}} sets {{done}} after an error is encountered.
> {code:go}
> func (r *Reader) Read() (array.Record, error) {
> if r.rec != nil {
> r.rec.Release()
> r.rec = nil
> }
> if !r.next() {
> // r.done is set if next() errors, so we always
> // return EOF instead of the actual error
> if r.done {
> return nil, io.EOF
> }
> return nil, r.err
> }
> return r.rec, nil
> }{code}
