I hacked at this a little today.  Right now I cannot deduce the tuple 
information as I cannot interrogate the inheritance hierarchies with the 
current Python value and type code.  There might be another way to do 
this, but I am not sure.  What is needed is for this kind of 
functionality to be in the Python/GDB value/type system. It is 
definitely now on the to-do list.
