From what I've been able to discern, [jmf's] actual complaint about PEP
393 stems from misguided moral concerns. With PEP-393, strings that
can be fully represented in Latin-1 can be stored in half the space
(ignoring fixed overhead) compared to strings containing at least one
non-Latin-1 character. jmf thinks this optimization is unfair to
non-English users and immoral; he wants Latin-1 strings to be treated
exactly like non-Latin-1 strings (I don't think he actually cares
about non-BMP strings at all; if narrow-build Unicode is good enough
for him, then it must be good enough for everybody).
Not entirely; most of his complaints are based on performance (speed
and/or memory) of 3.3 compared to a narrow build of 3.2, using silly
edge cases to prove how much worse 3.3 is, while utterly ignoring the
fact that, in those self-same edge cases, 3.2 is buggy.
And the fact that stringbench.py is overall about as fast with 3.3 as
with 3.2 *on the same Windows 7 machine* (which uses narrow build in
3.2), and that unicode operations are not far from bytes operations when
the same thing can be done with both.
