Hi Emil,

I liked very much your idea, but something bothers me.

IMO, this dynamic_cast should be hided by the library.
How about:

catch(read_error& x)
{
  if(info i = try_get_info(x))
  {
    // ... do something.
  }
}

There should be a way to inspect what there's in the info object too, IMHO.

I liked the << operator too for the throw statement.
