They are double comparisons, but it is iterating through a vector and comparing to values that were previously extracted from that same vector, so it's maybe not the optimal approach for what it's trying to do, but the == comparison should always evaluate to true when it finds the right value

Closing; turns out, the reference commits were added and modified in #104, which has the correct changes
