Declared in `<bdlc_queue.h>`

Return a reference to the modifiable value at the back of this queue. The reference will remain valid as long as the queue is not destroyed or modified (e.g., via `insert`, `remove`, or `append`). The behavior is undefined if the queue is empty. Note that this function is logically equivalent to: ` operator ‐ 1) `
