Is there a range like iota in phobos where step is a function? I want to specify begin/end and have the "step" be next = fun(prev). Should be easy to write, but don't want to reinvent the wheel.

````D
import std.stdio;
import std.range: iota;

void main()
{
    iota(10, 0, -1).writeln;
}

I think I misunderstood what was being asked here.
