For string related stuff — there’s not much in the stdlib that can replace the stuff in abseil. (Haven’t looked at Dawn in particular, though.) E.g. absl::StrF

For string related stuff — there’s not much in the stdlib that can replace the stuff in abseil. (Haven’t looked at Dawn in particular, though.) E.g. absl::StrFormat — no equivalent until std::format was standardized in C++20. absl::StrCat: You could use streams, but, ew. Also, StrCat is optimized to reserve sufficient size in advance, so it is more efficient than appending to a string or using a std::stringstream. absl::Cord. No equivalent in the stdlib.
