[go-nuts] Error-checking with errors.As() is brittle with regards to plain vs pointer types

Consider https://go.dev/play/p/jgPMwLRRsqe: errors.As(err, ) will not match if error is of pointer type. As a result, a library consumer needs to understand if a library returns Error or *Error. However, that is not part of the API spec as both returns would satisfy error if Error() is
