Hello,
Hi Emil,

[snipped]

I liked very much your idea, but something bothers me.
...
catch( read_error & x )
{
    if( info * xi = dynamic_cast<info *>(&x) )
        if( file_name * fn = xi->get<file_name>() )
            ......
}
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.
