On the other hand, you do want the compiler to be able to implicitly make one Exception object into another Exception object copies.

Example:
try { SomeBigFunction(); } catch(...) { //Determine exception type here }

I do not believe there is a standard way of doing this .
Doing so would at the very least require you to be able to access the current exception.

It seems it is general accepted that exception specifications are not helping as much as one thinks. But I wonder if a specification which only uses std::exception might be a good compromise:
void someFunction() throw ( std::exception );
It documents ...

On a conforming compiler, adding a non-empty exception specification generates the equivalent you gain is that, if someFunction or something it calls raises on non- std::exception -derived exception, std::unexpected is called, rather....
