 - Each variadic parameter, actually is an slice.

 The `std::jule::integrated` standard library is a major supporter of Integrated Jule's interoperability pillar. It provides a standard for widely used C/C++ definitions. This makes it possible to spend less time on C/C++ definitions that link to Jule code. In addition, it can not only make things easier, but also improve and simplify the implementation by providing algorithms for a number of tasks.
