SUre you could. The{} make it work.

EDIT: I sit corrected. My post is wrong.

No, you can't, and no they don't.

    lock(lk_var) {
        lock(lk_var2) {
            var = var2;
        }
    }

That expands to:

    for(int i=0; (i < 1) && !lk_lock(lk_var); lk_unlock(lk_var), i++)
    {
        for(int i=0; (i < 1) && !lk_lock(lk_var2); lk_unlock(lk_var2), i++)
        {
            var = var2;
        }
    }

You end up with an i scoped inside another i.

C++ has variable shadowing, so that works correctly.

    for (int i = 0; i < 5; ++i) {
        for (int i = 0; i < 5; ++i) {
            printf("hello\n");
        }
    }

prints hello 25 times.

Oh right. My brain was stuck in another language. Wow, I forgot how much I'd forgotten about C++.

Actually that's just C (name nesting)
