When a closure "captures" a variable it "lifts" the variable out of its local scope and effectively moves it into an anonymous object.

当一个闭包“捕获”一个变量时，它就会将这个变量提取出它的本地范围，移到一个匿名对象里。

Type Inference - the var keyword, which is necessary when using anonymous types, can also reduce redundancy in your other variable declarations.

类型推断—使用匿名类型时，关键字var必不可少。它还能减少你其他变量声明中的冗余。

Lambda functions (or "anonymous functions," as they are often referred to) are simply throwaway functions that can be defined at any time and are typically bound to a variable.

lambda函数(或者通常所谓的“匿名函数”)是可以随时定义的简单抛弃型函数，并且通常都与变量绑定。
