are matchers of different and arbitrary types. How can the library simplify this to always? 41Customizing not less_than<5> or greater_equal<5> If we know that these expressions are complements of each template 2: constexpr auto negate(not_t const &n) -> M { 3: return n.m; 4: } 45Customizing negate To negate a relational matcher, we can use the "inverse" operation. Where Op is e.g. std::less<>

binding: Not ideal, but has benefits Can annotate even if you don’t have control on source code Customizing the default behavior *mentioned in P2911 51User defined attributes? Proposed in P1887, discussed tagging information at the place of definition Requires control on the source code of the type Customizing the default behavior *mentioned in P2911 52One of my favorite features from Golang Adding information

of hash functions and their properties, techniques for hashing complex user- defined types, and customizing std::hash for specialized needs. Additionally, we (re)introduce a framework for experimenting hash functions and their properties, techniques for hashing complex user-defined types, and customizing std hash for specialized needs.2024 Victor Ciura | @ciura_victor - Unleashing 🦀 The Ferris
