Is there any Phobos function that collects "some" items of a

It's kind of embarrassing that I've been trying to find this
for hours now without success :(.
I think I know how to write this myself (though writing generic
stuff on ranges is not exactly straightforward), but surely
there is something for this and I am somehow missing it (even
AI can't help me)?
My use case is to parse a file format where a line is expected
to have 4 items. I am currently using `takeExactly(4)` but that
doesn't let me index on it, so I can only think of doing
inconvenient (and inefficient) stuff like `front, skip(1).front
...` to avoid having to write my own `toArray` :D. I couldn't
even find a method to take 1 item and advance the range! Am I
just looking at the entirely wrong places (std.range,
std.algorithm.iteration)??
```
import std;
alias takearray(int i)=(r)=>r.take(i).staticArray!i;
unittest{
iota(3).takearray!4.writeln;
iota(5).takearray!4.writeln;
}
```
