If you're looking for the mode of a set and you've been handed the set (meaning you weren't involved in building it) then you're going to have to iterate over each element and count. There's a quantum algorithm to do this more quickly, but the tech isn't there yet.

Why can't the elements be "put as a dictionary to set counters against them"? That's going to be the solution that most people hear will drive you towards. If you can't directly $count{thing}++ then you're going to have to $count{stringify(thing)}++ and find the mode(s) afterward.
