I want to say this should be equivelant to
apt[0] = Point(0, apt[0].Y)
which would not break mutability issues. However this breaks with the
current python trend (tuples could provide this functionality, but
don't).

To me, making apt[0].X = 0 require an explicitly new object is a
almost a showstopper. Are there any other purely reference semantic
languages on the CLI? Or are we treading on new ground?
