boost::make_variant_over —
Exposes a variant whose bounded types are the elements of the given type sequence.
template<typename Sequence> class make_variant_over { public: // types typedef variant< unspecified > type; };
type has behavior equivalent in every respect to variant< Sequence[0], Sequence[1], ... > (where Sequence[i] denotes the i-th element of Sequence), except that no upper limit is imposed on the number of types.
