std::exception_ptr

recently, I've been digging into std::exception_ptr.

i find it strange that in order to figure out what the error message is, what the type is, etc., that you have to re-throw the exception being held.

std::exception_ptr ex = faulty_func();

if (ex)
   try {
      std::rethrow_exception(ex);
   }
   catch (const std::exception& ex) {
      std::println("Here's what went wrong: {}", ex.what());
   }
   catch (...) {
      std::println("We're not quite sure what went wrong here");
   }

it seems like there should be a way to introspect on the exception that it's pointing to because, i mean, doesn't it have the address of the exception?

i'm going to look into this, and maybe i'll come up with a better version of std::exception_ptr.
