Discussion:

std::string::swap currently says for effects and postcondition:

Effects: Swaps the contents of the two strings.

Postcondition: *this contains the characters that were in s, s contains the characters that were in *this.

Specifying both Effects and Postcondition seems redundant, and the postcondition needs to be made stronger. Users would be unhappy if the characters were not in the same order after the swap.

Proposed resolution:

Effects: Swaps the contents of the two strings.

Postcondition: *this contains the same sequence of characters that were was in s, s contains the same sequence of characters that were was in *this.
