[MUC++] Artemy Pestretsov - Debugging constexpr Evaluation

Modern C++ keeps pushing more logic into constexpr/consteval: parsers, tables, DSLs, hashing -- code with branches, state, and failure modes that happen before your program ever runs. When something goes wrong at compile time, you can either try to guess the reason from the compiler’s notes or de‑constexpr it... and hope the runtime reproduction matches what the compiler actually did. In this talk, we’ll treat compile-time execution as something you can debug rather than guess. Using CLion’s constexpr debugger, we’ll step through constexpr evaluation, inspect values as they evolve, and see which if constexpr branches fired. We’ll also go deeper under the hood: how constant evaluation is represented, what makes debugging possible, and today’s limits.
