fail_compilation/test23216.d(23): Error: invalid `foreach_reverse` aggregate `r` of type `Range`
|
|
fail_compilation/test23216.d(23): `foreach_reverse` works with bidirectional ranges (implementing `back` and `popBack`), aggregates implementing `opApplyReverse`, or the result of an aggregate's `.tupleof` property
