About:
C++ Insights is a tool that reveals the hidden workings of the C++ compiler by showing the code as it is seen by the compiler. It performs implicit conversions, template instantiations, and shows the results of lambda expressions. This allows developers to understand complex language features and debug difficult compilation issues.

Key Features:

Shows implicit type conversions and constructor calls
Displays template instantiations and generated code
Visualizes lambda expressions and their underlying classes
Supports C++ standards up to C++20

Use Cases:

Debugging complex template metaprogramming issues
Learning how modern C++ features are implemented by the compiler
Understanding implicit code generation and object lifecycle

Alternatives:

Compiler Explorer – Shows assembly output, while C++ Insights shows the transformed C++ code
Clang's -ast-dump – Provides raw AST dumps, whereas C++ Insights presents readable C++ code
