C++ Templates Revised
summary
Second edition updates cover 14 years and three major C++ versions and show concrete changes: use of auto return deduction and when it hides lifetime bugs (example: string_view concatenation UB from implicit conversions), new template tools (fold expressions to avoid recursive instantiation and speed compile times, NTTP with auto for string separators), generic lambdas plus deduction guides to build an overloaded visitor, constexpr extended for real compile‑time computation, and requires/concepts replacing many enable_if workarounds.
