Por ejemplo, digamos que quieres tener una *operación de path* que permita actualizar ítems y devolver códigos de estado HTTP 200 "OK" cuando sea exitosa.

Pero también quieres que acepte nuevos ítems. Cuando los ítems no existan anteriormente, serán creados y devolverá un código de estado HTTP 201 "Created".

// performs the assignment and returns true. Otherwise, it returns false. The form
//
//	var perr *fs.PathError
//	if errors.As(err, &perr) {
//		fmt.Println(perr.Path)
//	}
//
// is preferable to
//
//	if perr, ok := err.(*fs.PathError); ok {
//		fmt.Println(perr.Path)
//	}
//
// because the former will succeed if err wraps an [*io/fs.PathError].
