Namespaces
namespace	xtd
	The xtd namespace contains all fundamental classes to access Hardware, Os, System, and more.
namespace	xtd::expressions
	The xtd::expressions namespace provides a lightweight, composable expression template framework for building and evaluating lazy, strongly-typed functional expressions from arbitrary callables.

Functions
template<size_t count>
constexpr auto	xtd::expressions::args ()
	Generates a set of positional placeholders that can be decomposed using structured bindings to build readable and composable expression templates.
