The use of e.g. `std::underlying_type_t<T>` replaces the older `typename std::underlying_type<T>::type`. The `_t` helper alias template (such as `std::underlying_type_t<T>`) introduced in C++14 offers a cleaner and more concise way to extract the type directly. See https://en.cppreference.com/w/cpp/types/underlying_type for details. -BEGIN VERIFY SCRIPT- sed -i -E 's/(typename )?(std::[a-z_]+)(<[^<>]+>)::type\b/\2_t\3/g' $(git grep -l '::type' ./src ':(exclude)src/bench/nanobench.h' ':(exclude)src/leveldb' ':(exclude)src/minisketch' ':(exclude)src/span.h' ':(exclude)src/sync.h') -END VERIFY SCRIPT-
