The function to get the typeid of an exception needs to be a member
function on exception_ptr. That way I can query
the typeid of a bag of exception_ptrs I get in a container, without
(re-)throwing any of those exceptions in the current thread,
as those exceptions may have been thrown on a different thread.

Again, this time more clearly:
received positive encouragement.
So that proposal should be resurrected, not just replaced with
something different.
