Maybe this is older. When I came to D around 2015, I learned that
there is `opApply` for forward iteration (`foreach`) and
`opApplyReverse` for reverse iteration (`foreach_reverse`). I
just tried defining a struct with `opApply`, but no
`opApplyReverse`, and then `foreach_reverse` on an instance (on
run.dlang.io). Doesn't work.
