For the record, io.StringIO should be quite fast in 3.3. (except for the method call overhead that Guido is complaining about :-))
AFAIK it's not the actual *call* of the method that is slow, but rather attribute lookup and creation of bound method objects. If speed is of the essence, code can cache the method object locally:
strio = io.StringIO() write = strio.write for element in elements: write(element) result = strio.getvalue()
And this is a great example of muddying code in stdlib for the sake of speeding up CPython.
