Oh wow, @discardableResult, Equatable, Element, I'm learning so much things in just one post! I've been thinking about how to make a result discardable so I don't need to use _ = ... but didn't know that such thing exists so I never look it up. Thanks!!!

If Element is Equatable, you can just use !contains(element)
