The slice objects support a single method "indices", which I have to
admit I've have not seen before a minute ago. (I've grepped through
the standard library and did not see it used anywhere). The slice
attributes start/stop/step are probably more useful, but I don't see
why those cannot be added to the range object.

How would that hurt reusing them for slicing?
