The current implementation of `is_narrowing_v` does not handle type conversions correctly. For example, `cpp2::impl::is_narrowing_v<std::size_t, int>` returns `false`, indicating that it mistakenly perceives the conversion from a signed `int` to an unsigned `size_t` as potentially non-narrowing.

Thanks! Looks good except for the conflicts -- can you take a pass through to resolve those? Then this should be ready to merge, thanks again. |
