Please post a patch to sf.net/projects/python (or its successor).

Several issues need to be taken into account:
- documentation and test cases must be updated to integrate the new API
- for slicing, you need to consider not only omitted indices, but also
  "true" slices (e.g. m[1:5])
- how should you deal with negative indices?
- should len(m) be supported?

Martin
