pointers don't come with a length?

Where is the problem if it points to something with a range interface?

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?
