--- Comment #1 from Seb <greensunny12 at gmail.com> ---
So summarizing the status quo in D is:

---
auto names2 = ["Sam", "Pamela", "Dave", "Pascal", "Erik"];
auto nameRange2 = names2.enumerate.filter!(a => a.value.length <=
a.index).map!(a => a.value);
nameRange2.writeln;
---

It's not too bad and I doubt that filterIndex would be accepted.
