Binary Half-Adders

Binary half-assed taxonomy bases the classification of snakes on any two of the three segments of neck, torso and tail, and produces two discrete results. For example, vermiform animals are sorted into separate categories according to either the length of their neck or their torso and sorted independently into separate categories according to the lengths of their neck and torso. Any pair of segments can be similarly dealt with.

This system will not work for intersex, hermaphrodite, neuter, genderfluid or genderqueer snakes, and only one category of snake can be feminist.
