> Currently, dictionary keys use a NullIterator to iterate them. However, physically, they are fully allocated in memory and are interpretable as a PrimitiveArray.
> This issue's main purpose is to have `keys` return a `PrimitiveArray`, so that users can use it as any other array.
> This will also allow to remove `NullIter`.
