[Python-Dev] odd "tuple does not support assignment" confusion...

l[0] += [1]

is the same as

l[0] = l[0] + [1]

Does that make the reason for the error clearer? The problem is the
attempt to assign a value to l[0].

It is not the same as

e = l[0]
e += [1]

which is the equivalent to

e = l[0]
e = e + [1]

This never assigns a value to l[0].
