My take on things is that doing unladen swallow really "right" will
require yet more incompatible changes; i.e., the result will either
still leave quite a bit of performance on the table, or else it won't be
compatible with the current specification of Python 3 and they'll
presumably have to call it Python 4.  And if Python 4 is as good as I
believe it could possibly be, then it might get wide acceptance before
Python 3 really has all that much uptake.  If I have to accept
incompatibility anyway, and Python 4 gives huge improvements while
Python 3's improvements are tiny or moderate, why not skip over Python 3?
