Review comment:
Yeah, I'm hesitant to read too much into the exactness of what the count
parameter does. as per docs (as I'm sure you've read) " Basically with COUNT
the user specified the amount of work that should be done at every call in
order to retrieve elements from the collection. This is just a hint for the
implementation, however generally speaking this is what you could expect most
of the times from the implementation." which, I think, is what makes it a
little confusing to know how to test. I'll remove the removal of the
duplicates, though
