It is wrong because it can assert. The code can generate a constant for every
inbound value that it asserts for, so trivially, it is wrong. If it were
correct, it would not assert for values it can handle. For it to be correct,
there would have to exist a value for which the code fails. The value that
failed for me was 0, not a terribly uncommon value.
