Subscripting and operator()

Apologies if this is a duplicate, the original one I sent didn't show up in my inbox nor on the yahoogroups page so I thought I'd better send it again. I am wrapping a class with an operator()(int, int) which I'd like to make available in Python as a subscript operator, but haven't been able to find any documentation on this nor guess the appropriate .def Is this possible and if so can anyone help? Regards, Chris.
