1) I use to_set not to remove duplicates but because Set#include? is O(1) while Array#include? is O(n). Not really needed with those data sizes, but feels conceptually more fitting. 2) In a bare Ruby script, yes, but Rails already includes set. Doesn't hurt to write it, though.

Curious, why to_set? To remove duplicates? If so, why not use array.uniq? And doesn't to_set require you to require set?-e.g. require 'set'
