Addresses UK 226 [CD1]
<array> must be added to this list. In particular it doesn't satisfy: - no swap() function invalidates any references, pointers, or iterators referring to the elements of the containers being swapped. and probably doesn't satisfy: - no swap() function throws an exception.
If <array> remains a container, this will have to also reference array, which will then have to say which of these points it satisfies.

Agree. The proposed resolution is incomplete. Further work required.

Issue 1099 also suggests adding move constructor to this.

Howard is to draft a note that explains what happens to references.
[ 2009-10 Santa Cruz: ]
Mark as NAD. No consensus for change.
[ 2009-08-01 Howard provided wording. ]
Proposed resolution:
Add a paragraph to 24.3.7.4 [array.special]:
template <Swappable T, size_t N> void swap(array<T,N>& x, array<T,N>& y);Effects:
swap_ranges(x.begin(), x.end(), y.begin());[Note: Outstanding iterators, references and pointers may be invalidated. — end note]
