Matt T. Proud 7999fd4710 errors: mention Is methods should not call Unwrap ... errors.Is internally unwraps the error until the error matches the target. Because of this, a user-authored Is method on an error type need not call errors.Unwrap on itself or the target, because that would make the unwrapping operation O(N^2). It is a subtle detail to remind authors for resource efficiency reasons.
