Right, thank you, Staven, that's the bit I missed.
[I knew about the common sense of slice in Python as a sysnonym of subsequence, 
meaning a partial copy; so I thought this different sense I just discovered, 
about slice _objects_ properly in Python, was about slice as commonly understood 
in other languages (D, C++, many more); but this is yet another, third meaning! 
;-). Like a slice sense2, but without pointer to the original object.]

They are more like (x)ranges, thus: an abstract representation of an interval.
