其实就是js的字符串字面量不是object，而weak是对object垃圾收集做手脚，所以不匹配。归根结底是语言设计问题。c#或java也有弱引用，传字符串字面量就没问题。

另外，string在使用被自动ToObject是约定俗成的东西，之所以weakmap实现中不这样，是因为基本类型虽然有对应的object形式，但设计上无共享语义（使得实现上可以共享而进行优化），你绕过了这个设计限制而已。简单讲：a=new String('abc'); b=a;则显然b与a指向同一片内存，但a=new String('abc'); b=new String('abc'); 则b与a是否指向同一片内存是未定义的。另外实在没必要用weakmap防止string这种小东西无法被回收，因为weakmap内部会根据这个string的地址生成另一个更复杂的标识对象，那个内存和cpu的overhead比起用map完全是倒退～

Sorry. Not a lawyer?So cute! Thank you^_^

your makefile is: mk/Makefile and I run: make then I get error: Makefile:1: **\* 遗漏分隔符 。 停止。 so what's wrong please?
