creates an end-of-stream
iterator i. This is a past-the-end iterator, and it is useful
when constructing a range.

creates an input
iterator i reading from . When reaches end of stream,
this iterator will compare equal to an end-of-stream iterator
created using the default constructor.

i fulfills the requirements for an input iterator.
