If I understand correctly
Pythons
  x.a[3]=1
will go through
__setitem__(__getattr__(x,"a"), 3, 1)

If so, it shall be easy (untested):

struct proxy {
  GetItem();
  SetItem():
};
struct X {
  proxy a;
}

class_<proxy>("proxy")
  .def("__getitem__", &proxy::GetItem)
  .def("__setitem__", &proxy::SetItem)
;

class_<X>("X")
  .add_property("a", &X::a)
;

Right?
