Automated patch, intended to be effectively a no-op. Context: https://groups.google.com/a/chromium.org/g/cxx/c/nBD_1LaanTc/m/ghh-ZZhWAwAJ?utm_medium=email&utm_source=footer As of https://crrev.com/1204351, absl::optional is now a type alias for std::optional. We should migrate toward it. Script: ``` function replace { echo "Replacing $1 by $2" git grep -l "$1" \ | cut -f1 -d: \ | grep \ -e "^content" \ | sort \ | uniq \ | grep \ -e "\.h" \ -e "\.cc" \ -e "\.mm" \ -e "\.py" \ | xargs sed -i "s/$1/$2/g" } replace "absl::make_optional" "std::make_optional" replace "absl::optional" "std::optional" replace "absl::nullopt" "std::nullopt" replace "absl::in_place" "std::in_place" replace "absl::in_place_t" "std::in_place_t" replace "\"third_party\/abseil-cpp\/absl\/types\/optional.h\"" "<optional>" git cl format ``` # Skipping unrelated "check_network_annotation" errors.
