Yah, but you also get
outfile.seek(some_random_place)
outfile += something
for free. This seems like what mathematicians call "abuse of
notation." While normally the rule is "consenting adults", I can see
folks with severe space constraints "reusing the buffer" with
something like
outfile.seek(0)
a_loop_of_somesort:
outfile += something
size = outfile.tell()
outfile.seek(0)
built_string = outfile.read(size)
I'm not a fan.
