I'm sorry, but what *is* it that you need if not the above?

     import std.stdio;

     class DerivedException : Exception { this() { super(""); } }

     void main() {
         try {
             // Code that throws some exception.
             throw new DerivedException;
         } catch (Exception ex) {
             writefln(ex.classinfo.name); // writes "DerivedException"
         }
     }

The above code writes "DerivedException" to stdout, which is the name of 
the most derived class ex is an instance of.

Am I missing something?
