I'd prefer it as a method on the Range class.  E.g. this looks more natural
to me:

(1..12).step(3) { |i| puts i.to_s }

And of course, you can write that in Ruby because Ruby classes are open.
For example:

class Range
    def step( step_size )
        i = 0
        while i < length
            yield start + i
            i += step_size
        end
    end
end

Note ... this is just a sketch.  I haven't tested it.  That's left as an
exercise to the reader :-)

Cheers,
        Nat.
