Not all two-pass processes on external streams build strings internally. At least, earlier you insisted that StringIO is not a string. > That's what the getvalue() method is for. True, but there's no guarantee a given process will ever invoke it. For example, I might read a file encoded as ISO-2022 into a StringIO, then read that StringIO normalizing it to another StringIO as NFD, then encode it to a file as UTF-8. Look Ma, no .getvalue!
