You *should* pass most ranges by value, just like how you should
rarely use `ref T[]` or `T[]*`. Ranges, like slices, are
typically already small references to some other container.
Where Phobos effs it up is not follow its own rules on range.save
in most cases... Jonathan talked about this at dconf IIRC in 2015.
