> If you're going to track the namespace on creation, you need to add serialization code for your `Sema::StdExperimentalNamespace` storage. But I'd suggest taking a different approach: just treat this as a cache, and do a lookup for `experimental` within namespace `std` if the namespace is requested and not in the cache.

Done. Could you please double check I got it correct?
