But I'm willing to bet that's going to be an anomaly. Python 3 came into
existence when it did so we didn't wait too long for Python 2 to get even
more of a foothold; the expectation is that long-term more non-Python 2
code will be written than not. There's no rush on Python 4 since there are
no plans to try and tweak something as drastic as str/bytes.
