Deprecate unsafe costructor, substituted by fromBufferUnsafe which explicitely marked suggest the caller to pay attention. Use enum class for id types instead of constants Make size constants more private Use internal Id_t alias to avoid huge template lines Remove and deprecate oguly names in favor of consistent names
