这两天过了遍Lua，Lua的一个语言特性是支持尾递归，这是我接触的第一个支持尾递归的语言（尾递归优化）
尾递归，是尾调用的一种类型，后者更加准确，因为实际的正确尾递归（Proper Tail Recursion）是不涉及递归的。尾调用是指一个函数里的最后一个动作是一个函数调用的情形：即这个调用的返回值直接被当前函数返回的情形。这种情形下称该调用位置为尾位置。若这个函数在尾位置调用本身（或是一个尾调用本身的其他函数等等），则称这种情况为尾递归，是递归的一种特殊情形。尾调用不一定是递归调用，但是尾递归特别有用，也比较容易实现。
我们直接的来看一下Lua中尾调用：
function f(x)

This script demonstrates how a bitcoin transaction is created and signed. Just pass in your own address and private key and it will prepare a transaction for you. You can then copy & paste that transaction into a webservice like Blockchain to send it. I wrote this mostly to understand better how it works. I sometimes had to "cheat" and look at t…
