Attributes are an underrated feature of the C++ language, in my opinion. I am saying this because I rarely see attributes used in code or samples featured in articles, videos, or talks. Although some of the standard attributes are targeted towards library implementers or address a limited number of scenarios (such as [[no_unique_address]], [[noreturn]], or [[carries_dependency]]), there are several that are quite useful in many situations. I refer here to [[nodiscard]], [[maybe_unused]], and [[deprecated]], which are the attributes I will talk about in this post.
