Talkat CppCon 2023 · on Monday, 2023-10-02· at 11:00· Cottonwood 8/9, 6700 North Gaylord Rockies Boulevard·
summary
Compares concrete C++ customization mechanisms and names the tradeoffs, not just the buzzwords: ADL, customization point objects, Concepts, tag_invoke are evaluated with real examples, code snippets and historical outcomes (swap, ranges, tag_invoke rejection for C++23). Proposes language-level customizable functions as a concrete solution and notes what failed and why, links to slides and code are provided, and compilation/diagnostic costs and implementation complexity are measured rather than handwaved.
