Developer releases C++ header-only library to transfer variable declarations between files

A developer has released VarSaver, a header-only C++ library built as a personal side project. The library extracts variable declarations from the main() function of one .cpp file and injects them into the main() function of another. It supports a range of declaration styles, including custom structs and multi-variable declarations like int a,b,c = 100, as long as the syntax is valid C++. Users need to call the save and load functions only once anywhere in their code, provided the code executes at runtime. The developer, who describes themselves as a competitive programmer, has shared the project on a public repository and is actively seeking community feedback.
