您将允许持久操作的非持久数据结构称为什么？

我有一个本质上可变的类，但允许一些“类似持久”的操作。例如，我可以像这样改变对象（在Python中）：

# create an object with y equal to 3 and z equal to "foobar"
x = MyDataStructure(y = 3, z = "foobar") 
x.y = 4

但是，代替以这种方式做事，有几种方法可以制作副本然后改变它：

x = MyDataStructure(y=3, z="foobar")
# a is just like x, but with y equal to 4.
a = x.using(y = 4)

这是用不同的方式复制x价值观。显然，这不符合维基百科给出的部分持久的定义。

那么你会怎么称呼这样的课程呢？准持久对象？持久化对象？持久对象排序？更好的是，有这方面的技术名称吗？

原文

I've got a class that is essentially mutable, but allows for some "persistent-like" operations. For example, I can mutate the object like this (in Python):

# create an object with y equal to 3 and z equal to "foobar"
x = MyDataStructure(y = 3, z = "foobar") 
x.y = 4

However, in lieu of doing things this way, there are a couple of methods that instead make a copy and then mutate it:

x = MyDataStructure(y=3, z="foobar")
# a is just like x, but with y equal to 4.
a = x.using(y = 4)

This is making a duplicate of x with different values. Apparently, this doesn't meet the definition of partially persistent given by wikipedia.

So what would you call a class like this? QuasiPersistentObject? PersistableObject? SortOfPersistentObject? Better yet, are there any technical names for this?
