may need further adjustment to thwart future optimizations (or a way to

The old classification system would interpret missing values as $0$,
|
||||
which could potentially trigger a match.
|
||||
The new classification system will always yield \tparam{FALSE}
|

regardless of predicate when values are undefined.

The defined value is available to adjacent expectations through use of
