1·This all can be done with no mutable state in the client code.
所有这些都可以在客户端代码中没有可变状态的情况下完成。
2·And this all can be done with no mutable state in the client code.
在客户代码中，这些都可以在不使用可变状态的情况下就能做到。
3·When mutable state goes away, almost all concurrency problems go away with it.
可变状态消失时，差不多所有的并发性问题也随之消失。
4·If you are creating a mutable class m, you should be prepared to write a lot more documentation about the treatment of references to m than if m were immutable.
如果您要创建一个可变类m，那么您应该准备编写比m是不可变的情况下多得多的文档说明，以说明怎样处理m的引用。
5·Out of this, we'll see if we can assemble a more dynamic and mutable requirements gathering procedure.
除此之外，我们还会看看是否能够组织起一个更动态更可变的需求收集过程。
1·More often than not, they involve mutable object state.
而它们时常也会涉及易变的对象状态。
2·Methods you call shouldn't depend on the mutable state of any object and should return fully reproducible and predictable results.
您所调用的方法不应依赖于任何对象的易变状态，而应返回可再生产、可预测的结果。
3·There's a loophole when synchronizing on a mutable field, however, which can break down mutual exclusion.
然而，易变域的同步中会有一个漏洞，它可能破坏互斥。
4·The dictionary is a heterogeneous, mutable container that relies on a key-to-data value mapping, rather than a particular numerical order to access items from the container.
dictionary 是一种异构的、易变的容器，依赖键到数据值的映射（而不是特定的数字次序）来访问容器中的元素。
5·The dictionary container in Python is also a mutable data type, which means you can change it after it has been created.
Python 中的 dictionary 容器也是易变的数据类型，这意味着在创建它之后可以修改它。
