If you disagree with this, I think *you* are being silly.

Ditto.
Come on now, that is just a silly argument.
And I think this is a silly response ;-).
And dictionaries are obviously irrelevant;
Not when talking about the semantics of English words.
The only serious reason that has been offered
for the current behavior is that people who do
not know better will sum strings instead of
joining them, which is more efficient. That is
a pretty weak argument for breaking expectations
and so refusing to do duck typing that an error
is raise. Especially in a language like Python.
(As Tim and Peter make clear.)
The absence of other responses is not the same as the absence of other
possible responses. Some people have better things to do than rehash all
the details of a past discussion.
Nothing I have said bears on whether I would have voted for or against
the current behavior. I have only addressed your to-me silly claim to
have 'confirmed' the correctness of one position.
