I think this needs a better explanation - what exactly is a hashset in
this context? Something like an array with a hash for faster lookup of
unique elements, or what?

In this context, by "hashset" I am indeed referring to a data structure similar
to an array, where each element would be unique, and lookups would be faster
than arrays for larger number of elements due to hash-based lookups.

Yeah, a fast lookup set type has long been on my "blue sky" wish list.  So +1 for pursuing the idea.
