Problem: - `std::identity` can cause dangling references. Solution: - Add `safe_identity` which safely moves from an rvalue-reference argument. Note: - I have had similar use cases, and written similar functions before, but I think never quite as succinctly as elucidated by Dr Walter Brown in https://www.youtube.com/watch?v=sIZUg9tN4sk. Thanks, Walter!
