Henry can correct me if I am wrong but dissect does not expect an adverb to
produce an adverb; *: av produces an adverb.  In the words of typical
functional programming languages, av is a Curried adverb which, in effect,
takes two arguments; for example, 1 2 3 and *: in the sentence,

   1 2 3 *: av
1 4 9

and *: av is a partial application.
