Absolutely! In the same way that saying the "Dugong Dugon" is a type of fish even though it's technically a Sirenia.

Here, "some swimming creature" is the totality of the objective, we aren't trying to do a crash course in marine zoology or trying to explain what a Sirenia is or what a fish technically means.

Saying it's perl-6 means that it's not say, lisp-like or some kind of prolog or haskell. It's a relatively swift approximation and that's the totality of the objective.
