I wonder if he's considered relaxing that restriction to allow at most
*one* try: finally: block, or any number of try: finally: blocks whose
finally: clauses are identical (which is effectively equivalent to a
single finally: clause).  He could then just compile the finally code
into an __del__ method on the generator-iterator.
