I'm working on an example for the cookbook that
allows integers to overflow to BigInteger and
has special paths when a constant is involved.

The idea is that x + 1 should just test if x equals Integer.MAX_VALUE,
and x+0, 0+x, x- 0 and -1- x need no guard at all
(the last one is due to the way integers are encoded).
