Expression closures are a shorthand method of defining simple functions that mimics lambda notation.

表达式闭包是定义简单函数的一种便捷方式，用来模仿lambda符号。

The closures notation strips away the boilerplate associated with inner classes, allowing a more compact (and more importantly, more direct) expression of the desired data operation.

闭包标注取消了与内部类相关的引用，允许更紧凑(重点更突出、更直接)地表示需要的数据操作。
