C++ Insights tool reveals compiler-generated code from Clang AST

C++ Insights is a Clang-based source-to-source transformation tool that exposes implicit compiler behavior, such as auto-generated constructors, copy assignment operators, and type casts, directly in readable C++ syntax. Its creator built the tool after researching modern C++11/14/17 features like lambdas and structured bindings, aiming to make hidden compiler operations visible to developers.
