std::move_iterator<Iter>::operator=

template< class U > move_iterator& operator=( const move_iterator<U>& other );		(until C++17)
template< class U > constexpr move_iterator& operator=( const move_iterator<U>& other );		(since C++17)

The underlying iterator is assigned the value of the underlying iterator of other, i.e. other.base().

The behavior is undefined if `U` is not convertible to `Iter`.	(until C++20)
This overload participates in overload resolution only if `U` is not the same type as `Iter` and `std::convertible_to<const U&, Iter>` and `std::assignable_from<Iter&, const U&>` are modeled.	(since C++20)
