Perhaps under:

Which C<sort> could, of course, also do (if it was decided that bully-boy,
fascist named parameters were the more appropriate default ;-).

No indeed. They are short-hand for indexing operations into an array (@_).
And array indices *do* start from zero.
In contexts like this (and others such as C<grep>) the omission of ^0
from a comparator would surely evoke a diagnostic.
