Constructs an iterator.

For the definition of /*maybe-const*/, see maybe-const .

1) Default constructor. Initializes parent_ with nullptr, and default-initializes it_.

2) Converting constructor. Initializes parent_ with it.parent_, and initializes it_ with an rvalue denoting the value held by it.it_.

• If it.it_ .valueless_by_exception() is true, the behavior is undefined.

3) Initializes parent_ with parent, and initializes it_ with std::forward<Args>(args)....

Parameters

it	-	a mutable iterator
parent	-	a pointer to ranges::concat_view
args	-	the arguments to initialize it_

Example
