“Thoughts on a more powerful and simpler C++ (5 of N)”
summary
Argues two concrete efforts: a Lifetime profile that statically diagnoses common dangling cases (string_view, iterators, raw pointers) with a released 1.0 spec and two implementations — MSVC extension that runs in IDE with real‑time squiggles and a Clang prototype that is ~5% compilation overhead and catches many real bugs; and a metaclasses prototype (Clang + cppx.godbolt) that generates accessors, async “active” objects, guarded/mutex wrappers and properties to remove boilerplate and replace many macro patterns, already in SG7 and exercising working examples.
