Overloading: The Bane of All Higher-Order Functions - Simon Brand [ CppCon 2018 ]

Lambdas, new algorithms, variant visitation and std::apply are just a few of the many additions which make use of the paradigm more natural, expressive and powerful. Unfortunately, passing overloaded functions or function templates to higher-order functions is not as simple as it sounds, which forces users to adopt various unsatisfactory workarounds. This talk will discuss a few solutions, show how C++ still has a way to go in providing language support, and examine some existing standards proposals which could help. Techniques discussed will include wrapping up overload sets in lambdas; maintaining noexcept specifications, return types, and brevity; global function objects; and avoiding subtle One Definition Rule (ODR) violations. — Simon Brand, Microsoft C++ Developer Advocate Simon is a C++ Developer Advocate at Microsoft.
