Discussion:
Requirements on iterators swapping allegiance would disallow the small-string optimization.
[ Resolved in Rapperswil by paper N3108. ]
Proposed resolution:
Add an exclusion for basic_string to the sentence
beginning “Every iterator referring to an
element...”. Add a sentence to 21.4.6.8/2 saying
that iterators and references to string elements
remain valid, but it is not specified whether they
refer to the same string or the other string.
