var co = require('co');

co(function*() {
    this.i = 0;
    yield loop1();
})

function* loop1() {
    console.log("loop:"+this.i);
    this.i++;
    yield loop2();
}

function* loop2() {
    console.log("loop:"+this.i);
    this.i++;
    yield loop1();
}

然而这段代码的循环次数永远只有

loop:0
loop:1
loop:2
loop:3
loop:4
loop:5
loop:6
loop:7
loop:8
loop:9
...
loop:3581
loop:3582
loop:3583
loop:3584
loop:3585
loop:3586
loop:3587

难道代码有问题还是本身就是这样的限制那么限制来源是ｃｏ模块迭代ｎｅｘｔ还是什么．．．以３５８７和ｙｉｅｌｄ为关键词并未找到相关问题
