I think that you've gotten so fixated on avoiding instrumenting the original throw site, that it's blinding to the readability issues with your solutions.
Well, I AM fixated on the requirement to instrument the original throw site. I wouldn't have cared except for the way it was attempted to enforce this requirement. But now that I've been made to care about it, I'll state that this is the fundamental problem with the library. To try to impose such a requirement on the libraries on application might use is not realistic. Boost is not the whole universe of libraries. My example was to demonstrate that was asserted to not be possible is in fact possible. I'm sure if I had nothing else to do I could make a more user friendly interface. But it wasn't my task to do so. I wanted to make the machinery visible for this discussion. Robert Ramey
