A tuple is a C++11 construction and it is built heavily on variadic templates.
A tuple is a variadic class template that stores an unlimited set of values of different types, defined when instantiating the tuple; for example:
tuple<int, int> x;
will store 2 integers.
tuple<string, int, bool> y;
will store one string, one integer and one boolean and so on.
