First, asking on the scipy mailing list will get you a better response.

Second, scipy_core does allow arrays of arbitrary Python objects, but
it doesn't do any kind of type-checking for those arrays. It is up to
you to populate the array with the kind of objects that you want.

  arr = empty((N, M), object)
  arr[i, j] = MyClass(i, j)

should work (can't check at the moment, though).

Please note that object arrays have always been tricky since Numeric,
so if you encounter strange behaviour, we would appreciate a report on
the scipy mailing list.
