I think the question Chris is really asking is why should unary plus
return ord() rather than any other function or method.
We could make unary plus of a string equal to the upper() method:
+"Hello world" # returns "HELLO WORLD"
or the strip() method:
+" Hello world " # returns "Hello world"
or len():
+"Hello world" # returns 11
or any other function or method we want. What is so special about ord(),
and what is the connection between ord() and `+` that makes it obvious
that +"a" should return 97 rather than "A" or 1 or 10 or something else?
It's not enough to just say that unary plus is unused for strings, you
have to justify why the average programmer will look at unary plus and
immediately think "ord".
