Statically linking libphobos
Hello, I am distributing a plugin written in D for another application. To make it easily distributable i would prefer to link libphobos statically. How would I do that and how would I do that with DUB? Thanks :)

Equivalent to take(repeat(value), n).

Sure, but: // This fails: repeat(8, 9).chunks(3).writeln(); // This works: repeat(8, 6).chunks(3).writeln(); Both are divisible by 3. Maybe it's a bug?

Looks like a bug. Doesn't happen with 2.072.0-b2, so it has apparently
already been fixed.

If I replace repeat with iota, or a literal range (like [1, 2
,3, 4]), I don't get the crash.
I don't see why I should not be able to use chunks with repeat.
If some property of repeat's range is missing to use chunks,
shouldn't I get an error message ?
Am I missing something ?
PS: the behavior has been reproduced on someone else computer.

This works:
repeat(8, 12).chunks(3).writeln;

Some more cases, perhaps someone more knowledgeable can help:
import std.algorithm;
import std.stdio;
import std.range;
int main()
{
[8, 8, 8, 8, 8, 8].chunks(3).writeln; // prints [[8, 8, 8],
[8, 8, 8]]
repeat(8, 6).writeln; // prints [8, 8, 8, 8,
8, 8]
repeat(8, 6).chunks(3).writeln; // prints [[8, 8, 8]].
Why?
assert([8, 8, 8, 8, 8, 8] == repeat(8, 6).array); // Passes
assert([8, 8, 8, 8, 8, 8].chunks(3).array == repeat(8,
6).array.chunks(3).array); // Passes
assert([8, 8, 8, 8, 8, 8].chunks(3).array == repeat(8,
6).chunks(3).map!(a => a.array).array); // Fails
return 0;
}
