Introduction

These are objects that pack elements of -possibly- different types together in a single object, just like pair objects do for pairs of elements, but generalized for any number of elements. It is closely related to the pair class (defined in header ): Tuples can be constructed from pairs, and pairs can be treated as tuples for certain purposes.
