           Summary: randomSample primes with constant
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: dawg dawgfoto.de



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.
