Sure, see the details at <http://docs.python.org/api/newTypes.html> and
consider that what you want will need to go into a PyMappingMethods or
PySequenceMethods structure -- not well documented online, but just take
a look in the Python sources at the way the type objects for lists &c
are defined, and take it from there.
