But then the error message is not true anymore because tuples *would*
support item assignment when the old and new value are the same. Which
leads to strange things like code that may or may not raise that
exception, depending on implementation details:
t = (1, 2)
t[0] = 1 # Maybe okay -- maybe not.
t[1] += 0 # Same here.
I'd find that quite odd.
