Current implementation of NOEXCEPT_SCOPE will not work, you cannot rethrow exception outside the catch block, this will simply terminate (via std::terminate) the program. In other words NOEXCEPT_SCOPE macro will simply call std::terminate on exception and will lost original exception. But if NOEXCEPT_SCOPE will accept the code that should be runned w/o exceptions, then it can catch exception and log it, rewrite it in this way. Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
