How is difference_type relevant?

any practical problems with using std::size_t, but likewise I'd be surprised if there were any practical problems with always using std::ptrdiff_t for difference_type.

Probably not, but as there's iterator_traits<>::difference_type, there's no need to always use std::ptrdiff_t. Maybe size_type should be added in TR2? :p Olaf
