“Modern C++ Interfaces..."
summary
Argues that richer C++ features produce simpler, more robust interfaces by embedding policy and judgment into code; demonstrates replacing a naive memcpy with staged implementations selected by type traits (is_trivially_copyable, nothrow copy) and constexpr if to allow mutually incompatible branches to compile; shows SFINAE-based DWIM interfaces using enable_if and return-type tricks; builds a small toolkit of composable template AST evaluated at compile time (variable templates, fold expressions, operator-overloaded predicate trees) to generate SFINAE constraints — code and slides on the CppCon2017 GitHub.
