Yes. But the cost of copying the value and the cost of the exception are separate.The argument is not about performance, it's about loosing values.
If you implement popFront as { popFront(); // current popFront return front; }Then no value is lost with Exception. If an Exception is thrown, this is dubious anyway, because the value is likely to be irrelevant anyway.
