import std.random, std.range, std.stdio;

void main()
{
    foreach (_; 0 .. 100)
    {
        immutable seed = unpredictableSeed();
        writeln(seed, " => ", randomSample(iota(100), 1, Random(seed)).front);
    }
}

--------

The random generator is assigned to the Range only after it was primed and the default constructed random generator always returns the same first value.
