Fixing C++ with Epochs
summary
Proposes using modules as an opt‑in per‑module edition system so code starts with a directive selecting a version and modules with different versions compile to a common IR, enabling gradual migration. Concrete change: make the implicit narrowing conversion (calling serialize(stream, int) with a float) implicit narrowing conversions ill-formed in the new edition so users must use static_cast; aims for per-module language versions and automated, backwards‑compatible migration without ABI changes.
