(ranges TS)

The InputIterator concept is a refinement of Iterator, adding the requirement that the referenced values can be read (via Readable) and the requirement that the iterator category tag be present.

Notes

Unlike the input iterator requirements in the C++ standard, InputIterator in the Ranges TS does not require EqualityComparable.
