Hmm. That's true of Python 2 (mostly - once an operation yields a
long, it never reverts to int, whereas a string will shrink if you
remove the wider characters from it), but not, I think, of Python 3.
The optimization isn't there any more. At least, I did some tinkering
a while ago (on 3.2, I think), so maybe it's been reinstated since. As
of Python 3 and the unification of types, it's definitely possible to
put that in as a pure optimization, anyhow.
