Step through range in D

Question

Is there a way to create a step in D ranges? For example, in python, range(1, 10, 2) gives me

        [1, 3, 5, 7, 9]

all odds within 1 .. 10

Is there a way to do this in D using foreach?

    foreach(x; 1 .. 10) {
 }

I know I can use iota(start, end, step), but I also want to add an int to the very beginning and I don't know how to convert type Result to an int.

What do you mean by "add an int to the very beginning"? And the result of `iota(1, 10, 2)` *is* `int`. — kennytm, Jun 21 '13 at 21:07
I'm building an array of primes -> iota(3, 16, 2). I need to append a 2 to the beginning. — Phil Kurtis, Jun 21 '13 at 21:18

chain([2],iota(3,16,2));

chain concatenates ranges lazily

or you can go the other way around with filter!q{a==2||a&1}(iota(2,16));
