It's not a full answer, but try to add `import std.array;` or its analog
in mir if exists

Ok... didn't have this on my radar.
I suggest using Mir instead of Phobos if possible:
https://run.dlang.io/is/NBTfwF
/+dub.sdl:

dependency "mir-random" version="~>2.1.1"
+/
import mir.random.algorithm;
import mir.algorithm.iteration;
import mir.ndslice: sliced, iota, map, member;
void main()
{
S[] arr;
arr.length = 42;
// using each
arr.length.iota.each!((i, ref el) => el.i = i)(arr);
// or using each and member
arr.length.iota.each!"b = a"(arr.member!"i");
// or using assign
arr.member!"i"[] = arr.length.iota;
auto res0 = rne.sample(arr.map!((ref el) => el.i), 1);
// or using member
auto res1 = rne.sample(arr.member!"i", 1);
}
struct S { size_t i; }
I will try to adopt this... Thanks a lot!

Thanks. But I have another one:

Does not depend, on whether I use (ref el) or just el... And
should not depend on that ;)

Could somebody tell me, why

size_t[] arr;
arr.length = 42;
arr = arr.length.iota.array;

refuses to compile?
