This is a regression. It is fixed in mir-random v2.1.2.

Thanks. But I have another one:

´´´
import mir.random.algorithm;
import std.experimental.all;

void main()
{
        S[] arr;
        arr.length = 42;
        arr.each!((i, ref el) => el.i = i);
        auto res = rne.sample(arr.map!((ref el) => el.i), 1);
}

struct S { size_t i; }
´´´

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

I have updated template constraints.

The problem that looks like Phobos map does not define all 
required primitives like popFrontExactly. I suggest using Mir 
instead of Phobos if possible:
