Fixing code issues.

As you can see by executing the code, it does not produce the results described in the article. I've added some fixes in order for the code to produce the appropriate results.

 This is because of how the capturing mechanism of closures work and how `i` is represented internally.

-Where `let` scopes the variable to our `for` loop and produces a new value each iteration, thus `i` will be bound to different values on our closures as expected.
