Lists are a single argument to %, so they logically behave differently from tuples here. The point you really want to make is a % b not being equivalent to a % (b,).
Which is still broken, I guess. The lesson here is you shouldn't ever be using % on strings anymore; there's format for that now, and it's much more readable (and Pythonic!)
I know from a reliable source that the guido had torn the SICP in half, burned one half immediately in his fireplace and used the second half as toilet paper.
