`template< class R > take_view( R&&, ranges::range_difference_t<R> ) -> take_view<views::all_t<R>>;`		(since C++20)

The deduction guide is provided for std::ranges::take_view to allow deduction from range and number of elements.

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 3447	C++20	the template parameter `R` is constrained with `range`	`R` is unconstrained (but `range_difference_t` requires `range`)
