- diff_target_values holds its inline values in a std::array (a type
with an empty user-provided constructor, as the serializer's buffers,
so that -Weffc++ is met and they stay uninitialized) and declares its
move members as deleted
- auto for an iterator and a cast, and parentheses around a %
json::diff() instructions are unchanged within noise (Apple clang,
twitter and citm_catalog).
