Defined in header <experimental/ranges/concepts>
template <class T> (ranges TS)
concept bool Regular = Semiregular<T> &&
EqualityComparable<T>;

copyable,
default constructible, and equality comparable. It is satisfied by types that
behave
similarly to built-in types like int, and that are comparable with ==.
