`#include <CGAL/tuple.h>`

## Definition

An object of the class `cpp11::tuple` represents a heterogeneous tuple of elements of the types specified in parameters, which are in variadic number.

There is actually no class in namespace `CGAL::cpp11` with this name, but a using declaration which imports a class from another namespace. By order of priority: the one in namespace `std` is used (provided by C++0x), if not found, then the one in namespace `std::tr1` is used (provided by TR1), and finally, the fallback solution is taken from Boost.

Parameters

The parameters `...` are the value types.

Free functions and helper classes

Some free functions part of the standard interface of `tuple` are also brought in namespace `CGAL::cpp11` with using declarations, these are `make_tuple`, `get`, `tie`. Like in C++0x, the `get` function template is specialized so that it can take `std::pair` as argument. Two standard helper classes are also provided for convenience (`tuple_size` and `tuple_element`).
