There are
https://dlang.org/library/std/algorithm/mutation/reverse.html
and
https://dlang.org/library/std/range/retro.html
both require a bidirectional range, which Indexed, luckily is.
I wasn't clear enough. I meant getting back the underlying
`Source` range with _its_ elements in the order that the indices
specify. This wouldn't be possible in the generic case, but the
special case when indices.length == source.length, it should be
possible. So indexed(myRange, [2, 3, 5, 1,
4]).sourceWithSwappedElements should return a typeof(myRange)
with the elements swapped in that order.
