Problem: - Default destructors (and constructors) are in `.cpp` files. This prevents the compiler's optimizer from inlining them when it thinks inlining is appropriate (unless LTO is used). - Forward declarations can prevent some optimizations, such as inlining of constructors and destructors. Solution: - Remove them or set them to `= default` and let the compiler handle the generation of them. - Remove unneeded forward declarations.
