Hop - A Language to Design Function-Overload-Sets

Explore a comprehensive conference talk from CppNow 2021 that introduces hop, a Domain-Specific Embedded Language (DSEL) for designing complex function-overload-sets in C++. Dive into advanced techniques for creating homogeneous variadic functions, overloads with trailing and non-trailing default arguments, and alternatives to preprocessor-based function overloading. Learn about overload resolution, implicit conversion, concepts, and various building blocks for function parameters. Discover type generators, repetition techniques, sequencing, and alternatives in function design. Gain insights into defaulted parameters, forwarding parameters, template argument deduction, and adapting existing functions. Examine practical examples, local type deduction, and small type forwarding to enhance your C++ programming skills.
