Returning a None-value is pretty useless. Why not returning self, which would be
the resulting list in this case? Returning self would make the
language a little bit more functional, without any drawback.

Then nested calls like

a = [].append('x').append('y').append('z')

would be possible with a containing the resulting list

['x', 'y', 'z'].

That is the way I expect any append to behave.
