Well, if you want to get a slice which refers to the same thing as that slice
but includes elements which are in what is being sliced but which aren't in
that slice, you can only get the slice that you want be reslicing whatever the
slices came from. So, that means that you have to have a range which refers to
all of the elements that you want your target range to refer to and possibly
more and then either slice that range to exactly the elements that you want or
pop off elements until you get the range that you want. Doing that generally
requires knowing how many elements to pop off or the indices to slice, which
basically means that you have to keep track of indices.
In general, it doesn't work very well to increase a range so that it covers
more elements. They're designed to be reduced, not increased, and so the more
"D" way of doing things with ranges essentially goes against what you're
trying to do, forcing you to come at the problem from a different angle. And in
this case, it sounds like that probably means keeping track of indices.

Thanks for reply. It shows that there are different tools for different
jobs and I should use appropriate tool for specific job.
