Note however, - * that it's extremely difficult -- if not impossible -- to assert that a - * function doesn't raise any Ruby exceptions at all.

But no, I don't think they are useful any longer. - * - * - When an inline function attributed `noexcept` actually doesn't throw - * any exceptions at all: these days I don't see any difference in - * generated assembly by adding/removing this attribute. C++ compilers - * get smarter and smarter. Today they can infer if it actually throws - * or not without any annotations by humans (correct me if I'm wrong). - * - * - When an inline function attributed `noexcepr` actually _does_ throw an - * exception: they have to call `std::terminate` then (C++ standard - * mandates so). This means exception handling routines are actually - * enforced, not omitted. This doesn't impact runtime performance (The - * Itanium C++ ABI has zero-cost exception handling), but does impact on - * generated binary size.
