Surely, but you should have both available in any case.  I think there's a good 
argument that for all random number distributions, there should be a function 
_and_ a range implementation, so depending on your needs do either:

     auto dist = someDistribution(/* ... parameters ... */, rng);
     foreach (x; dist.take(10))
     {
         writeln(x);
     }

... or:

     foreach(_; 0 .. 10)
     {
         auto x = some(/* ... parameters ... */, rng);
         writeln(x);
     }

Of course in practice sometimes the range might just wrap the function, or the 
function might contain within a static instance of the range.
