FWIW, JSR-310 currently has 18 non-test usages of increment/decrement,
vs 42 uses of add. Less, but certainly used.

The real value in increment/decrement is that it becomes a simple
mapping from operator to method
a++ = increment(a)
a-- = decrement(a)
a + b = add(a, b)
This makes it easier to see what the intent would have been were the
real operators safe.
