So an library might choose to implement the string class so that the class itself has (data member) space for “short” strings so that no allocation is necessary until the size of the string is no longer “short” for some value of “short.” Given this implementation how would capacity() be implemented?In particular would capacity() ever return a value less than the “short” string limit?

What is happening is that we are creating a temporary container as a copy of our original container using the iterator range constructor and then swapping the contents of the our temporary container with our original container.

request to reduce memory use.” Why is deque’s description different than vector and string?

Because deque doesn’t have a capacity() member function.

So the standard doesn’t want to say that the implementation must reduce capacity() to size(). While I’m all for giving implementers latitude for their implementations, I think the committee has underspecified this call.
