Yes, these are things I've been wondering about. The use-case for an append-only StringIO is obviously overlapping with the use-case for using ''.join(). However, the implementation I'm proposing is better than ''.join() when writing very small strings, since there's a periodic consolidation. > As a special case, you may consider that .truncate(0) doesn't really > need to realize the buffer first. True. Also, seek(0) then read() could use the same optimization.
