Even if it was faster, I would still prefer +=.
foo.extend(yada) doesn't look beautiful to me at all.
After all, why do we have, e.g. == operator so we can say if a == b and
not a.equals(b)? Because the former is simply better looking, and to me the
same applies to += versus .extend() or even .append()
