Dear all,
As suggested by several people, I have started to rely on range_difference<T>::type in all places of the library.
I have also updated the docs w.r.t new concepts and are working on polishing them.
1.35 will introduce a new function
template< class T > BOOST_DEDUCED_TYPENAME range_difference<T>::type size( const T& r );
Really, you're returning the difference_type and not the size_type?
Yes, that was the intension. Iterators don't have a size_type per se, and so it complicated the whole thing a little to make the user worry about this.

Would it be better to use a meta-function 'make_unsigned' which converts signed type to its correspondent unsigned type? For example: signed int => unsigned int ::std::ptrdif_t => ::std::size_t etc. I've used it for my iterator range: http://tools.assembla.com/cbear/browser/trunk/cbear.berlios.de/range.
