Does anyone know a construct to turn a lambda into an infinite

I though I've seen this around somewhere but can no longer find 
it.

I can't find anything to do it. That seems weirdly absent.  You 
can abuse recurrence to do it.


    Random gen;
    foreach(v; recurrence!((a, n) => uniform(0, 100, 
gen))(0).dropOne.take(10))
        writeln(v);
