Must be more complicated than a trivial derefencing:
import std.range;
void main() {
auto r = 5.iota;
auto p = &r;
foreach (e; *p) {
}
}
Having said that, I swear there is a seemingly-over-the-top help of D
for foreach loops, which I can't remember now. Similar to what you said,
it works with a certain type of construct by thinking outside the box.
Do others know what I am trying to remember?
