What is the equivalent of Rust's chunks_exact()[1] method in D? 
I want to iterate over a spitted string two chunks at a time.

$ rdmd --eval '"hello world".chunks(2).each!writeln'
he
ll
o
wo
rl
d

$ rdmd --eval '"hello 
world".chunks(2).map!"a.array.length".each!writeln'
2
2
2
2
2
1

Note the .array; each chunk is a range type.

$ rdmd --eval 'typeid("hello world".chunks(2).take(1)).writeln'
std.range.Take!(Chunks!string).Take
