有没有办法访问隐藏在另一个范围内的局部变量的值?

I know if a variable is global, the you can always access its value by preceding the variable name with ::... but is there a way to access the value of a local variable that has become hidden inside another scope?

我在想这样的事情:

void f() {
    int x = 1;
    {
        int x = 2;
        //access the value of the variable x (with the 1 in it) inside here
    }
}

如果语言不支持这一点，那么我完全可以接受一些hacky解决方案.
