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

It's kind of embarrassing that I've been trying to find this

now without success :(.

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)??

What's wrong with just using std.array.array?

So I was indeed looking at the wrong place. It's not very
intuitive to me that a function that acts on ranges is not in
std.range but in std.array.
I guess the idea is to keep std.range pure (all functions take
and return ranges, not slices/arrays/HashMaps etc.)?
