I read a little bit about this in the Python Extension building
docs.  Basically, this works by setting a global var, as in 
  
 if ( i>=v.size()) {
  PyErr_SetString(PyExc_IndexError, "index out of range");
  return NULL;
 }
 return v[i];

But for it does not appear to be working just right for me yet
(returning NULL is causing a problem for some of my vector types
because the elements cannot be initialized with an int).  I'll poke
around the docs some more for a solution.

Thanks,
