On dice(): I think this is one case of what is in practice a random number
_distribution_, akin to uniform().
My own instinct is that as much as possible, random number distributions should
come in two forms -- functions, and ranges. So, it should be possible to go,
foreach(_; 0 .. 10)
{
writeln(uniform(0.0, 1.0));
writeln(dice(10, 5, 7));
}
but equally well to go,
auto uniDist = uniformDistribution(0.0, 1.0);
auto biasedDice = diceDistribution(10, 5, 7);
foreach(u, d; lockstep(uniDist, biasedDice).take(10))
{
writeln(u);
writeln(d);
}
(I'm sure you can find something to improve in how I've written the second
example, but you get the idea of how the distributions could behave:-)
