[issue23275] Can assign [] = (), but not () = []

Agreed.  To take one example, David Beazley's PyCon 2015 talk would have been broken by the suggested change!  (See https://www.youtube.com/watch?v=MCs5OvhV9S4, at around the 42:17 mark.)

If there's any code change resulting from this issue, I also think it should be to make assignment to `()` legal.
