Need to start studying that module abit more I think. I'm looking at the docs now and I see there are actually a couple of isomethings().

Your xslice (or mine) would still be better than islice when the step
size is large; islice has to iterate over all the skipped elements
which could be wasteful if the input is indexable. Also islice doesn't
support negative values for start, stop or step which xslice does.
