So what should "abc" + "def" result in, if addition is different from
concatenation? No, adding strings should concatenate them. And other
arithmetic operators make sense, too; Python doesn't happen to
implement str-str or str/str, but some languages do:

> "abc"+"def"-"abc";
(1) Result: "def"
> "abc"-"b";
(2) Result: "ac"
> "foo bar asdf qwer"/" "*"##";
(3) Result: "foo##bar##asdf##qwer"

PHP has separate addition and concatenation operators, and it doesn't
help anything (granted, the biggest problem is that every other
language we work with uses + to concat strings, so it's an easy source
of bugs); having multiple operators for "add the elements of these
arrays" and "add these arrays together" is really orthogonal to the
general issue of adding and concatenating needing different operators.

But as Steven said, the way different types are free to react
differently to the same operators is *GOOD* design in Python. Java
doesn't let user-defined types override operators, so all those
possibilities are closed. You can argue that it's poor design in NumPy
(and people will argue the contrary position), but it's definitely not
a flaw in Python-the-language.
