为什么不能重载三元运算符？
Why can't a ternary operator be overloaded?
我一直对此很好奇，但从未找到可靠的答案或易于理解的解释。我试过其他运营商，效果很好。这个运算符尤其有趣。我只是无法理解它。
stroustrup 的常见问题解答：
There is no fundamental reason to disallow overloading of ?:. I just
didn't see the need to introduce the special case of overloading a
ternary operator. Note that a function overloading expr1?expr2:expr3
would not be able to guarantee that only one of expr2 and expr3 was
executed.
