This is so, so irrelevant. Even if it isn't optimized out (which
it probably is), pushing a zero to the stack is so extremely
cheap that you'd probably not notice it, especially compared to
reading something from a file.
Im pretty new to D, can somebody tell me how i would do this?
Is this(lazy int i){ ... a solution?
That's actually more expensive than just sending the zero!
