如何在数据模型内部，进行update?

如题

class UserAccount: HandyJSON {
required init() {
super.init()
let json = "{/"id/":/"1/"}"
// 在对象内部进行自我update, 类似于 YYModel的 self.yy_modelSet(withJSON: dict)
// Cannot pass immutable value as inout argument: 'self' is immutable 报错
JSONDeserializer.update(object: &self, from: dict)
}
}

Start by reading JSONDeserializer.update and the UserAccount initializer shown in the issue, then reproduce the reported immutable-self error. The issue does not name a source file or test; done would require a clearly supported answer or behavior for updating an object from inside its own initializer, with the limitation documented or tested.
