Ugh. I really don't want to maintain a separate expected-file for this,
especially not if it's going to be hard to test. Can we choose another
way of exercising the code path?

Another issue with this code as written is that on 32-bit-UV platforms,
at least some vompilers will give warnings about the constant-false
predicate. Not sure about a good solution for that. Maybe it's a
sufficient reason to invent uint8_numeric so we don't need a range check.
