Named Arguments from Scratch
summary
Live coding builds a small named-arguments library in C++17 using Boost.Hana and Compiler Explorer, showing an adapter that accepts a hana::map of keys to values, extracts a hana::tuple in the required order, and uses hana::unpack to call the function — it compiles and prints the expected result. The demo implements a user-defined literal for argument names and a operator= overload to produce hana::pair entries, discusses perfect forwarding, default-argument handling, and posts the full Argo-based code on GitHub.
