I believe that the current behavior is exactly what I want almost all the
time. If I have a list, I most often want to append to it; if it's a tuple
or integer, then of course I couldn't, and what I meant is adding it and
making a new object.

The problem really doesn't show up for me. This design is an excellent
pragmatical choice.
