I'm surprised you bring PHP as an example, as it appears their foreach

Yeah, but the point is, there is a rewind() method. That is called every
time on foreach().
It seems what you are after is forward ranges. Those are able to
"rewind" when you are done with them. It's just not done through a
rewind method, but via saving the range before iteration:
```d
foreach(val; forwardRange.save)
{
...
break;
}
// forwardRange hasn't been iterated here
```
