Task背后的实现是进程池.//下面这个例子使用了LazyLazy<Task<string>> lazyTask =newLazy<Task<string>>(() =>{returnnewTask<string>(() => { Console.WriteLine("Task Body working......");return"Task Result"; }); }); Console.WriteLine

可以发现,在这里没有必要用任何的return语法,新定义的函数总是返回我们提供的表达式的值。 然而,这样还不够,它只是会返回一个新的函数,在REPL中我么可以看到是一串字符串(如下所示),这就是函数的值,但这样的形式并不方便我们使用新函数。 #<user$eval__43$fn__45 user$eval__43$fn__45@ac06d4>...
Combining functions like this—so that the return value of one function is passed as an argument to another—is calledfunction composition. In fact,this isn’t so different from the previous example, which used recursion,because recursion continually passes the result of a function to another func...

Maps are function If you pass a key to a map, it will return that key’s value, or it will return nil if the key is not found: (inventors "Lisp") "McCarthy" (inventors "Foo") nil Get, handle missing (get a-map key not-found-val?) ...
