Effects: Equivalent to: underlying_.set_brackets(STATICALLY-WIDEN<charT>("{"), STATICALLY-WIDEN<charT>("}"));

template<class ParseContext> constexpr typename ParseContext::iterator parse(ParseContext& ctx);

Effects: Equivalent to: return underlying_.parse(ctx);

template<class FormatContext> typename FormatContext::iterator format(maybe-const-set& r, FormatContext& ctx) const;

Effects: Equivalent to: return underlying_.format(r, ctx);
