    struct in { /* implementation-defined */
};

struct in1 { /* implementation-defined */

struct out1 { /* implementation-defined */

(ranges TS)

    struct fun { /* implementation-defined */
};

struct min { /* implementation-defined */
};

struct max { /* implementation-defined */
};

struct begin { /* implementation-defined */
};

struct end { /* implementation-defined */
};

These classes are TagSpecifiers for use with ranges::tagged.
The name of a specifier is also the element name it corresponds to. For instance, ranges::tagged<std::pair<int, int>, tag::min, tag::max> provides a set of named accessors named min and a set of named accessors named max.
