I have an array which I call powerSet on and I get a result of MapResult. I have tried to foreach or front/popFront and even each() on it but I can never get the result as the same array type that I started with.
What is MapResult(the algorithm that generates the result lazily?) and how do we easily iterate over the results like we would with an array?
