Convenience alias template for naming a ranges::tagged wrapping a std::pair.
A TaggedType is a function type S(T), where S is a TagSpecifier and T
tagged_pair<S1(T1), S2(T2)> is an alias for ranges::tagged < std::pair <T1, T2>, S1, S2>
Notes
Because a function type is used to "glue" the tag specifier and the corresponding element type together, the usual parameter type adjustments apply. In particular, top-level cv-qualifiers are removed and array types are adjusted to pointers: tagged_pair< tag::in ( const int * const ), tag::out ( int [ ] ) > is ranges::tagged < std::pair < const int *, int * >, tag::in, tag::out >
