1·In the case of this single threaded benchmark, it is quite safe for Hotspot to safely elide the lock.
在这个单线程化的基准测试中，Hotspot可以非常安全地将锁省略掉。
2·To reflect idiomatic use, code examples in this document elide semicolons using these rules.
为了习惯这种用法，该文档中所有示例中的分号都将依据以上规则省略。
3·Even though an implementation is allowed to elide the copy, a viable and accessible copy constructor (or move constructor, if we're talking about a move) should still be present.
虽然实现是允许省略拷贝，一个可行的和可访问的拷贝构造函数(或移动构造函数，如果我们谈论的是一个移动)应该是仍然存在的。
