Oh, Python's design wasn't perfect - that's a pretty much impossible
goal anyway. Sometimes you don't learn what you ought to have done
till it's been in production for a while - that's why, for instance,
these happened:

https://wiki.theory.org/YourLanguageSucks#Fixed_in_Python_3

You'd have to be completely omniscient to avoid that kind of
misjudgment, and breaking backward compatibility is such a major cost
that sometimes design errors just have to be kept. But you'll still
end up with something far cleaner than would come from ad-hoc
undirected changes; it'll be a design with warts, rather than a lack
of design.

Yeah, this does make things hard. But that dynamism is a fundamental
part of Python's design, even if it's used by almost nothing. I'd say
this isn't proof of a design error, just a consequence of a design
decision. Python isn't for everyone, nor for every task - sometimes
it'll be too slow for what you want. So be it! There are plenty of
places where it's good. And there are similar languages (hi Pike!) for
when you want a bit more performance.
