Keynote: What C++ is and what it will become
summary
C++ combines low‑level hardware mapping with high‑level abstraction and claims to keep the cost where it’s used: zero-overhead abstraction. The language adds move semantics so large return values avoid copies, and constexpr lets the compiler compute constants like a weekday at compile time. Concepts give early, readable template errors; modules promise dramatic compile savings—176 bytes of source can expand to 400K in GCC or 1.2M in clang today—so modules reduce parse size and speed build times. Tools and checkers hunt ownership leaks.
