Listed here, if setting up copy2 throws, we possess the same dilemma because i’s destructor now also can throw, and if so we’ll invoke std::terminate.
It is impossible to Recuperate from all mistakes. If recovery from an mistake is not possible, it is necessary to swiftly “get out†inside of a properly-outlined way.

By stating the intent in source, implementers and equipment can offer far better diagnostics, for instance getting some courses of problems via static analysis, and conduct optimizations, like taking away branches and null tests.
