I have implemented my own version of Ruby's Array uniq-method (Ruby docs - Class array) as a monkey patch on Array.
Method-impl.:
require 'set'

self.each { uniq.add(it) }
uniq.to_a
end
end
Usage:
require_relative "own_uniq.rb"

As a small personal exercise, I'm trying to implement a notion of higher-kinded types in Rust using type-level defunctionalisation based on the "Lightweight higher-kinded polymorphism" paper.
Here's some of the work I've done so far:

This is a bit of a continuation of the question N queen problem-like (+rooks and a different goal).
The goal is to quickly place Q queens and R rooks on a chessboard with a side of Q+R squares, of course without the queens and rooks being able to attack each other, to obtain the maximum sum ...

I decided to create cli(s) in C++. For instance a music player which will play music from my library via commands player play muse or player shuffle.
