Lisps often use just one tag bit, to distinguish between an immediate
object and a heap object. With int/long unification, Python shouldn't
be able to tell the difference between an immediate int and a heap int.
I seem to remember that KCL (and maybe GCL/AKCL) uses heap-consed ints
just like Python does. It doesn't seem to be disastrous.
