it seems that the iterator type itself must be CC and CA. For a given
iterator a, *a must be convertible to iterator_traits<X>::value_type
(we'll use T for this below).

For pointer containers, this currently poses quite a problem because of
its indirected interface: the conversion could succeed if T was defined
as iterator_traits<X>::reference, but the ReadableIteratorConcept does
not allow T to be a reference type.

The only thing I can come up with is that pointer container iterators
does not satisfy the ReadableIteratorConcept, but only the

Does that make sense?
