Abstract: https://compiler-research.org/presentations/#USINGSTDCPP2026

> Despite its high-performance capabilities, C++ is not the first programming language that comes to mind for rapidly developing robust applications, mainly due to the long edit-compile-run cycles. Ongoing research in the compiler-research.org group aims to provide practical, interactive capabilities for C++, enabling dynamic interoperability, rapid prototyping, and exploratory programming, essential for data science and other applications. This talk explores how interactive C++ can be leveraged for various scientific usecases and teaching. Attendees will also learn how to leverage Clang as a library to build a simple C++ REPL for incremental compilation and introspection, integrating this layer with the Python runtime.

> The second part of this talk covers CppInterOp, a production-grade C++ interoperability library based on LLVM and Clang that provides compiler-as-a-service capabilities for seamless cross-language integration. CppInterOp formalizes a stable, backward-compatible API that enables dynamic languages to harness the full power of modern C++ without sacrificing expressiveness or performance. We explore applications of the CppInterOp library in the context of Python/C++ bindings, interactive C++ notebooks with xeus-cpp, and WebAssembly.
