I don't think I like the asymmetry that this would
introduce into + on lists. Currently

    [1, 2, 3] + (4, 5, 6)

is an error because it's not clear whether the
programmer intended the result to be a list or
a tuple. I think that's a good thing.

Also, it would mean that

    [1, 2, 3] + foo == [1, 2, 3, "f", "o", "o"]

which would be surprising and probably not what
was intended.
