Thanks for the answer, I'm thinking about it. The problem with generic 
iteration is that you must at least know the step for the loop, that 
means, from my point of view, design and develop a type that enclose 
only the possible values for the set, this way you can ensure the 
constraint in the steps, but, what if the steps is known only at running 
time, even worst: what if the steps change from a loop to another? 
That's a problem.
