Re: [boost] difference_type size()?

iterator_range returns a signed size. Is this correct? IMO it should return size_t.

boost\range\iterator_range_core.hpp: difference_type size() const { return m_End - m_Begin; }

Random thought: It seems like advance_begin and advance_end could be used to create a strictly negative size. Returning difference_type allows this to be detected while a size_type does not. - Rhys
