《Lua程序设计(第2版)》 6.3 正确的尾调用(proper tail call) Lua是支持尾调用消除(tail-call elimination)的,如下面对函数g的调用就是尾调用。 1functionf(x)returng(x)end 尾调用之后,程序不需要保存任何关于函数f的栈(stack)信息,即不耗费任何栈空间。 尾调用方法可用于编写状态机(state machine),类似于g...

说python中不能实现optimization of "tail-call elimination,"可是我google中搜索了一下发现了这个 http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/474088 可是由于不太了解functional-programming 所以the optimization of "tail-call elimination" 也不知道确切的意思,所以也不知道下面的代码写的对不对。 ...
and by definition, you can't have two calls in tail positions (well, you can in conditionals, but then it's one tail-call per branch). But you can do tail recursion elimination on the second call, so you only have to recurse down the left branch and can iterate down ...
产生这种函数帧更动代码与 “jump”(而不是一般常规函数调用的代码)的过程称作尾调用消除(Tail Call Elimination)或尾调用优化(Tail Call Optimization, TCO)。”。通俗地讲,也就是如果一个函数(caller)的结尾是调用另一个函数(callee),或者以callee的返回值作为caller的返回值,或者什么都不返回。那么尾调用优化就...

Tail call elimination allows procedure calls in tail position to be implemented as efficiently as goto statements, thus allowing efficient structured programming. 尾调用优化让位于尾位置的函数调用跟 goto 语句性能一样高,也因此使得高效的结构编程成为现实。 WikiMatrix If an implementation uses tail call...
This is wasteful and can be optimized. Here lies the concept of tail call elimination, through which we consider the callee as an extension of the caller. How it can be done in WebAssembly: return_call The following shows the WebAssembly equivalent of our factorial example, with tail calls ...
