I did consider that, but I found myself wondering what would happen if I did 
something like this:

///////////////////////////////////////////////////////////
import std.random;

@property ref MyRNG rndGen()
{
     // etc. ...
}


void main()
{
     auto s = randomSample(iota(0, 100), 10);
     // and do something with s
}
///////////////////////////////////////////////////////////

Calling randomSample like this ought to involve rndGen; but given that 
randomSample is in std.random, would it use my self-defined rndGen, or that from 
std.random?

OK, I probably should and certainly could have tested this myself ... :-)  I was 
just wondering if there was a _trivial_ way to override the default RNG type.
