template< class T, class... Args > std::any make_any( Args&&... args );	(1)	(since C++17)
template< class T, class U, class... Args > std::any make_any( std::initializer_list<U> il, Args&&... args );	(2)	(since C++17)

Constructs an any object containing an object of type T, passing the provided arguments to T's constructor.

1) Equivalent to return std::any(std::in_place_type<T>, std::forward<Args>(args)...);

2) Equivalent to return std::any(std::in_place_type<T>, il, std::forward<Args>(args)...);
