Hi,
iterator_range returns a signed size. Is this correct? IMO it should return size_t.
given two arbitrary valid random access iterators (from one range) let you know the distance between them
it is either positive or negative (or 0) dependent on the order of the given iterators
i'd say difference type should be ptrdiff_t in the general case
We're not talking about difference_type. We're talking about the return type of size().

sorry, i misread the initial message if the definition of size is how many times one need to ++begin to reach end then it's clearly must be something like size_t but if size is (end - begin) for random access iterators it well may be a signed integer, e.g. ptrdiff_t -- Pavel P.S. if you notice a grammar mistake or weird phrasing in my message please point it out
