The documentation of

Yes, that's correct. This is the overload of `repeat` in question:
https://dlang.org/phobos/std_range.html#.repeat.2
Take!(Repeat!T) repeat(T)(T value, size_t n);
Repeats value exactly n times. Equivalent to take(repeat(value),
n).
Examples:
import std.algorithm : equal;
assert(equal(5.repeat(4), 5.repeat().take(4)));
The variant of repeat that takes a second argument returns a
range with a length; it is not an infinite range, unlike the
first overload of repeat. So for the OP's code:
repeat(8, 10).chunks(3).writeln();
This will throw an AssertError because 10 is not evenly divisible
by 3.
